As mentioned in the previous article "How to Buy a Piano Within Your Budget" always buy the best piano in it's class that you can afford.
This leads us to the subject of digital pianos. They have come a long way. The sound is immensely improved. The touch and sensitivity has the feel of an acoustic piano. Also features such as recording directly into the piano is a great plus. Being able to instantly listen back to your performance is a fantastic way to objectively hear where you can improve your playing. Some even have a slot for an SD card or USB port so you can transfer your stellar performances to your computer and send them to friends and the world!
With that being said I'd like to mention a few key points in your purchase of a digital piano.
1. Buy a full size 88 key piano. You'll feel like you're really playing a piano. While they have a 76 key piano and a dreaded 61 key piano for less money, in my opinion it is not worth it. Please stick to the 88 full-sized keyboard.
2. Purchase only keyboards that have a weighted key action. This will give you the feel of a real piano. Touch sensitive keyboards have a spring loaded action and is quite ineffective with shading (crescendo, forte, piano etc) and have a sloppy feel at best. Stick to the weighted action.
3. Which brands should you buy? While selecting a piano is very personal according to your tastes (sound, feel, response etc) I would stick to the better brands such as Yamaha (which I own and love), Roland and Kawai (I recently traded my Yamaha U3 upright for the Kawai CA93 with a wood soundboard and it is beyond amazing!!) So stick with the best. The extra money you might have to spend is worth it!
4. Last is Features. If you want more sounds other than basic piano look for keyboards that have strings, horns, rhythm sections etc. Want to record your performances? Look for various recording features (direct to piano, USB port, SD card etc)
Also see how you feel with the layout of the keyboard. Are the functions and features presented in an intuitive way, is there a learning curve to use the features and if so how much?
I hope this helps you in choosing a digital piano you'll really enjoy!
