You want a beginner keyboard that helps you learn, practice, and enjoy playing without getting buried in confusing specifications. The biggest differences among these three options are key feel, number of keys, sound and learning features, connectivity, and portability.
If developing a more piano-like playing feel is your priority, an 88-key weighted digital piano makes the strongest case. If portability, sound variety, or guided learning matters more, a 61-key touch-sensitive keyboard can be easier to live with and carry.

How We Picked
You need clear criteria for choosing a beginner keyboard so the instrument supports the way you actually want to learn. We prioritized key action and key count, sound and speaker capability, learning features, portability, and connectivity for headphones, computers, mobile devices, and music software.
We also considered included accessories, power options, ease of setup, and whether each keyboard leaves enough room for your skills to grow. Because prices and marketplace ratings can change, this guide focuses on relatively stable product features rather than a temporary price or review count.
Casio CT-X700
The CT-X700 combines a portable 61-key design with Casio’s AiX sound source, 600 tones, 195 rhythms, touch response, and USB-MIDI connectivity. That combination makes it useful for beginners who want more sound variety than a piano-focused instrument while still having velocity-sensitive keys for expressive practice.
At about 4.3 kg, it is considerably easier to move than a typical 88-key digital piano. It can run from the included AC adapter or six AA batteries, which adds flexibility for lessons, rehearsals, or rooms where a convenient outlet is not available.
The main tradeoff is key feel. The keys are touch-responsive but not weighted, so players whose main goal is traditional acoustic-piano technique may prefer an 88-key weighted model.

|
Pros |
Cons |
|---|---|
|
✅ AiX sound source with 600 tones |
❌ Non-weighted action is less piano-like than an 88-key weighted model |
|
✅ Compact 61-key design and about 4.3 kg weight |
❌ 61 keys provide less range than a full 88-key piano |
|
✅ 195 rhythms for accompaniment and practice |
❌ Feature-rich controls can take time to learn |
|
✅ USB-MIDI, headphone output, AC power, and optional AA-battery operation |
Long-Term Value
The CT-X700 can remain useful beyond the first few lessons because it combines touch response, a broad sound library, accompaniment features, recording functions, and USB-MIDI connectivity. A beginner can start with basic practice and later use the same keyboard for arranging, MIDI input, or casual performance.
Return on Investment
The practical value comes from how many roles one keyboard can cover. Instead of buying separate beginner, composing, and portable keyboards, you can use the CT-X700 for everyday practice, song ideas, lessons, and computer-based MIDI work. Whether that is worthwhile depends on which of those features you will actually use.
Situational Benefits
|
Situation |
How It Helps |
|---|---|
|
Daily Practice |
Touch-responsive keys and a large tone library give you more ways to vary scales, chords, accompaniment practice, and songs. |
|
Lessons and Learning |
USB-MIDI and the built-in lesson functions provide several ways to combine the keyboard with structured practice. |
|
Travel and Rehearsals |
Its roughly 4.3 kg body and optional battery operation make it easier to move between home, lessons, or rehearsals than most 88-key weighted instruments. |
|
Composing and Jamming |
Hundreds of tones and accompaniment rhythms give you a broad palette for sketching arrangements and trying different musical styles. |
Educational Value
Touch response lets beginners practice playing notes at different dynamic levels rather than treating every keystroke the same. The lesson functions, rhythms, tones, and USB-MIDI connection also give you several ways to keep practice varied.

Versatility
The CT-X700 works well as a learning keyboard, songwriting tool, MIDI input device, and portable practice instrument. Its biggest advantage over a piano-focused model is the combination of sound variety and portability rather than an acoustic-piano-style key action.
Looks
The CT-X700 uses a compact molded case with an integrated display and controls. Its relatively shallow footprint is useful when you need a keyboard that can fit on a desk, stand, or smaller practice area.
Best For
Beginners and intermediate players who prioritize sound variety, portability, touch-sensitive keys, and USB-MIDI over a weighted 88-key piano action.
Who Should Avoid It?
If your main goal is traditional piano study and you specifically want the resistance and full range of an 88-key weighted instrument, the DEP-20 is the more relevant option in this comparison.
Key Benefits
- AiX sound source with 600 tones
- 61 touch-responsive full-size keys
- Compact 4.3 kg design
- 195 accompaniment rhythms
- USB-MIDI connectivity
- AC adapter or six-AA battery operation
Donner DEP-20
The Donner DEP-20 is the piano-focused option in this group. It provides 88 full-size weighted keys with adjustable touch response, giving beginners the full keyboard range and more key resistance than the two 61-key Casio models.
It also offers 238 tones, 128-note maximum polyphony, USB-MIDI connectivity, audio connections, recording functions, a backlit display, and dual 25W amplification. The portable package includes a sustain pedal, sheet-music stand, power adapter, and instruction manual.
The tradeoff is portability. An 88-key weighted instrument takes more floor or stand space and is less convenient to carry than a compact 61-key keyboard. Choose it because you value the key action and full range, not because you need the lightest option.

Pros |
Cons |
|---|---|
|
✅ 88 full-size weighted keys with adjustable touch response |
❌ Larger footprint than a 61-key portable keyboard |
|
✅ 238 tones and 128-note polyphony |
❌ Heavier to move between lessons or rooms |
|
✅ Sustain pedal, sheet-music stand, and power adapter included in the portable package |
❌ Players may eventually prefer a more substantial pedal setup |
|
✅ USB-MIDI plus audio inputs and outputs |
❌ More controls and features than a basic piano-only model |
Long-Term Value
The 88-key range and weighted action mean beginners interested in piano do not immediately outgrow the keyboard simply because they need more notes or more resistance under the fingers. USB-MIDI and recording features also give the DEP-20 uses beyond basic practice.
Return On Investment
The DEP-20 makes the most sense when you would otherwise expect to upgrade from a lightweight beginner keyboard to a weighted 88-key model fairly quickly. Starting with the full range can reduce that particular reason for replacing an instrument later.
Situational Benefits
|
Situation |
How It Helps |
|---|---|
|
Daily Piano Practice |
Weighted keys give your fingers more resistance than the two non-weighted Casio models and provide a playing experience closer to a traditional piano. |
|
Lessons And Study |
The full 88-key range accommodates repertoire that extends beyond the range of a 61-key keyboard. |
|
Home Playing |
The dual 25W amplification provides considerably more onboard amplifier power than the compact Casio models in this comparison. |
|
MIDI And Recording |
USB-MIDI and recording features let you connect the piano to compatible computer-based music workflows. |
Educational Value
For students planning to spend significant time on piano repertoire, the weighted action and 88-key range can make the transition between digital and acoustic pianos more familiar. The adjustable touch response also lets you tailor how the instrument reacts to playing strength.

Versatility
The DEP-20 can handle piano practice, MIDI input, basic recording, layered sounds, and home performance. Compared with the portable Casio models, its strongest advantage is the full 88-key weighted action rather than grab-and-go convenience.
Looks
The matte-black design is understated and practical. Because the keyboard is full size, plan for more width and a sturdier stand or dedicated practice position than you would need for a compact 61-key board.
Best For
Beginners and advancing players who prioritize 88 keys, weighted action, piano-oriented practice, and room to grow into more demanding repertoire.
Who Should Avoid It?
If you expect to carry your keyboard frequently, have very limited space, or care more about lighted lessons and battery-powered portability, one of the Casio models is easier to manage.
Key Benefits
- 88 full-size weighted keys with adjustable touch response
- 238 tones and 128-note maximum polyphony
- USB-MIDI connectivity
- Audio inputs and outputs
- Dual 25W amplification
- Sustain pedal, sheet-music stand, and power adapter included with the portable package
Casio LK-S250
The LK-S250 is designed around beginner engagement. It combines 61 full-size touch-responsive keys with Casio’s Key Lighting System, built-in lesson functions, 400 tones, 77 rhythms, and Dance Music Mode.
It is also the lightest model in this comparison at about 3.4 kg. The keyboard can run from its AC adapter or six AA batteries, and its built-in carrying handle makes it particularly convenient for lessons, classrooms, or casual playing away from a permanent setup.
USB-MIDI allows connection to compatible computers and smart devices, while a microphone input, audio input, pedal connection, and headphone/output jack expand what you can do with it. The USB connector is micro-B, so some modern computers or phones may require the appropriate cable or adapter.
Like the CT-X700, its keys are touch-responsive rather than weighted. That keeps the keyboard light, but an 88-key weighted instrument is a better fit when acoustic-piano-style resistance is a priority.

Pros |
Cons |
|---|---|
|
✅ Key Lighting System and built-in lesson functions |
❌ Non-weighted keys are less piano-like than the DEP-20’s weighted action |
|
✅ 61 full-size touch-responsive keys |
❌ 61-key range is shorter than a full-size piano keyboard |
|
✅ USB-MIDI, microphone input, audio input, and pedal connection |
❌ Micro-B USB may require an adapter with some newer devices |
|
✅ About 3.4 kg with optional six-AA battery operation |
❌ Less suited to players specifically seeking an acoustic-piano-style action |
Long-Term Value
The LK-S250 can continue serving a beginner after the first lessons because its touch response, 400 tones, rhythms, Dance Music Mode, and USB-MIDI support extend beyond the Key Lighting System. Its usefulness depends on whether you continue to value portability and creative features as your playing develops.
Return On Investment
The strongest practical value is having lesson tools, touch-sensitive keys, portable power options, and creative features in one lightweight instrument. That can be attractive for a learner who might otherwise need separate devices for guided practice and casual music-making.
Situational Benefits
|
Situation |
How It Helps |
|---|---|
|
Daily Practice |
Lighted keys, lesson functions, touch response, and built-in songs give beginners several forms of visual and musical guidance. |
|
Learning For Kids |
The Key Lighting System can make note-following more approachable for learners who respond well to visual cues. |
|
Travel & Casual Play |
The 3.4 kg body, carrying handle, and optional AA-battery operation make it the easiest of these three keyboards to move frequently. |
|
Creative Sketching |
Dance Music Mode, 400 tones, 77 rhythms, and USB-MIDI provide more creative options than a basic lesson-only keyboard. |
Educational Value
The LK-S250 combines visual guidance with touch-responsive keys, built-in lesson functions, and scoring features. Those tools can give new players more structure, while touch sensitivity introduces the idea that playing strength affects musical dynamics.

Versatility
The LK-S250 can cover beginner lessons, casual playing, basic music creation, and USB-MIDI use with a compatible device. Its main distinction is that those features come in a particularly light, battery-capable package with illuminated keys.
Looks
The compact enclosure and integrated carrying handle make the LK-S250 look less like permanent furniture and more like a portable practice instrument. The illuminated keys also provide an obvious visual element during guided learning.
Best For
Beginners, younger learners, parents choosing a first keyboard, and self-directed players who value guided lessons, lighted keys, portability, and battery operation.
Who Should Avoid It?
If the main goal is developing on an 88-key weighted action or regularly playing repertoire that needs the full piano range, the Donner DEP-20 is the better match among these three.
Key Benefits
- Key Lighting System and built-in lesson functions
- 61 full-size touch-responsive keys
- 400 tones and 77 rhythms
- Dance Music Mode
- USB-MIDI through a micro-B port
- About 3.4 kg with optional six-AA battery operation
FAQ
How Many Keys Do I Need?
A 61-key keyboard covers a large amount of beginner, pop, chord, songwriting, and general practice material while keeping the instrument relatively compact. An 88-key keyboard gives you the full piano range and becomes more important if you plan to study repertoire that regularly uses the upper and lower ends of the keyboard.
If you are unsure, think about your available space, how often you will move the instrument, and whether your goal is general keyboard playing or more traditional piano study.
Do I Need Weighted Keys?
Not every beginner needs weighted keys. Touch-sensitive non-weighted keys can work well for casual learning, songwriting, electronic music, and portable practice.
If you specifically want a playing feel closer to an acoustic piano, plan to study traditional piano repertoire, or expect to move regularly between digital and acoustic pianos, an 88-key weighted model is usually the more suitable starting point.
What Features Should I Prioritize?
Prioritize the features that affect your actual practice: key feel, key count, touch response, sound quality, headphone support, portability, power options, and useful connectivity. Learning aids can help if you will actually use them, while USB-MIDI is valuable if you expect to connect the keyboard to music apps or computer software.
Can I Practice With Headphones?
Yes. All three models provide a headphone or output connection suitable for quiet practice. Check the connector size for your particular headphones because you may need an adapter depending on the plug you use.
Which of These Keyboards Can Run on Batteries?
The Casio CT-X700 and Casio LK-S250 can operate from six AA batteries as an alternative to their AC adapters. That makes them more convenient for portable practice. The Donner DEP-20 is better treated as an AC-powered home or studio instrument.
Is a 61-Key Keyboard Too Small for a Beginner?
No. A 61-key keyboard can be a practical starting point for many beginners and is easier to store and transport. The limitation becomes more important when your repertoire requires notes beyond its range or when you specifically want the dimensions and feel of a full 88-key piano.
How to Choose Between These Three
Start with the type of playing experience you want. Choose the Donner DEP-20 when full-range weighted keys are the priority. Choose the Casio CT-X700 when you want a portable keyboard with a larger sound and rhythm library. Choose the Casio LK-S250 when guided learning, lighted keys, low weight, and battery-powered portability matter most.
Because marketplace preferences and reviews can change, base your final decision on the current product specifications and the features you personally need.
Before You Buy
- Measure your space: an 88-key instrument needs considerably more width than a 61-key keyboard.
- Choose your key feel: weighted action favors piano-style practice; lighter touch-responsive keys favor portability.
- Think about movement: the LK-S250 and CT-X700 are much easier to carry regularly.
- Check your connections: confirm headphone, pedal, USB, and audio connections match the devices you plan to use.
- Check the live listing: bundles, prices, seller availability, ratings, and review counts can change.
Wrapping Up
There is no single key action or feature set that fits every beginner. The best choice depends on what will make you practice consistently and whether your priority is piano feel, portability, sound variety, or guided learning.
Choose the Donner DEP-20 if you want an 88-key weighted digital piano for piano-focused practice. Choose the Casio CT-X700 if you want a lighter 61-key keyboard with the AiX sound source, a large tone library, rhythms, and USB-MIDI. Choose the Casio LK-S250 if you want an especially portable learning keyboard with lighted keys, lesson functions, and battery operation.
Check the current Amazon listings before buying because prices, bundles, availability, ratings, and review counts can change.
