The Privia PX100 digital piano is a discontinued Casio model. It has been upgraded in the newer models of PX110 and PX120. However, if you can find a used one for a good price (and in good condition) this can be a great way to get a digital piano on the cheap.
Let's look at what is generally considered the two most important features of any digital piano: keyboard action and sound.
The Casio Privia PX100 digital piano uses scaled hammer action on its 88-key keyboard. This recreates the acoustic grand piano feel with the lower notes being slightly heavier than the higher notes. So the PX100 would be good for a beginner or hobbyist pianist that wants a cheap digital piano that emulates the feel of an acoustic. The later Privia models improved upon the keyboard action. So the PX110 and PX120 models will feel even more like an acoustic piano.
But remember, our goal with the PX100 is to get a cheap alternative that is still a good quality digital piano. So don't let that turn you off from this digital piano. You could pay thousands of dollars for an even better keyboard feel, but price is a factor in everyone's decision. And remember, keyboard action is very subjective. You can read reviews of people that say the PX100 perfectly recreates the acoustic piano feel, while others say it doesn't. The rule of thumb is try it out for yourself.
The sound quality of the PX100 is very good. It emulates the sound of a grand piano using Casio's Sound Source technology. Realistic sound is vitally important. Poor sound recreation can lead a digital piano to dust collecting status.
One big feature that doesn't need to be overlooked is that the PX100 is very light and good for portability. This lightness, coupled with the fact that it has weighted keys that emulate an acoustic piano feel, give you the best of both worlds: acoustic feel and portability. It only weighs 27 pounds. So it's easy to carry, but I'd suggest you get a bag or case to protect it during transportation.
Some other features you can expect include 10 tones, 30-song built-in library, reverb, chorus, 32-note polyphony, 20 built in rhythms, metronome, and more.
In conclusion, if you can find this discontinued model in good condition for a cheaper price than a new PX110 or PX120, then the Casio Privia PX100 digital piano could be worth the investment. Read some online reviews about it. Some people absolutely swear by this digital piano, while others say "Just go with newer technology." But when you're working on a budget the PX100 can be a good choice.
