Digital piano is an economy and alternative to pianos, before , it is important to understand what perspectives you should be looking at when shopping for a digital piano, so that you can make the smartest purchase and find the digital piano right for you.
What type of piano do you need?
There are several types and styles of digital pianos out there, and each one has its unique features and suit certain people. Below are detailed descriptions of each type that help you decide which one works best for you.  
Digital console pianos Digital console pianos sit up against the wall and some are even designed to function as an elegant piece of furniture. Although much lighter and easier to move than acoustic pianos, console pianos are intended to remain stationary in your home. These pianos will have everything you need to replace the form and function of a traditional upright piano. They usually come with built-in speakers, pedals, and base, and their realistic sound and weighted key action are intended to mimic a real piano.​
Stage pianos Stage pianos are designed for use on-the-go or with a live band. They can have many of the same features as console pianos including weighted keys and real piano sound, but they look more like keyboards or synthesizers than acoustic pianos. Portable and stage pianos do not have built-in bases or pedals so you will need to get a separate pedal unit and folding stand. They may have built-in speakers, but they are intended for use with amplifiers or PA systems.​
Electronic Keyboards They have many more sound options than typical digital pianos and can produce a wide range of electronic tones. They can be used for stage performance or studio production. However, they aren’t always designed to mimic the true piano experience. They may not have weighted keys and may not have the full 88. Even though they have many sounds to play with, the piano sampling may not be as realistic as a dedicated digital piano.​
Workstation Essentially a computer built into a keyboard, a workstation has everything: top-of-the-line sound samples, sequencing, recording and editing, and computer integration. Workstations come in 61-, 73-, and 88-key models. These babies can be quite expensive, but if you’ve got big musical dreams, you may want to try one out.
Synthesizers You can still buy a good ol’ synthesizer and manipulate waveforms, filters, and work with both analog and digital sounds. Today’s synthesizers come with more sounds to work with than older models, letting you go to town with some good preset sounds.
MIDI Controller MIDI controller keyboards are also geared towards musical production and control other devices using MIDI, and usually do not have speaker systems.

How to choose your digital piano

Now, understanding what type of piano you should be considering, there are many other aspects should been taken into consideration when you make the purchase decision.
  • Budget – There’s a pretty broad range in cost when it comes to shopping for your own model. The higher in price you go, the more advanced features are included and most importantly, the nicer the overall piano is (in terms of build, key-make, and the like). How much cash you’re willing to spend will determine this.
  • Key Count — Digital pianos come in various key counts, as in how many keys attached to the piano itself. When deciding, just keep in mind that the standard piano key count is 88. You can also go a bit lower with 76 or 61 keys if you want a small piano or perhaps don’t need the full 88. However, we don’t recommend going any lower if you’re planning on investing in a digital piano (also keep in mind, some classical pieces can only be played with 88 keys!). Especially if you’re starting to learn, we insist you start with the legitimate amount of keys. We actually mostly recommend 88-key models in here with a few exceptions.
  • Key Make —The traditional acoustic piano keys are weighted, but there are numerous other makes out there including semi-weighted and synth-action. Aside from these weighted-types,  you have some fancy tech words companies use to make the keys sound as realistic as possible. Touch sensors,
  • Weight/Portability — Some of these are technically portable, being that they’re just the piano itself and the stand be folded and what not. However, others are strictly made for traveling. Will you be on-the-go a lot? This may be important for you.
  • Accessories Included – We’re talking piano stands, headphones, speaker systems (most have one built-in, albeit not too high of quality), sheet holder, etc.
