cass and others,
there is a huge difference between the piano sound of the old privia sound (PX310 and PX320) and the new PX330. It's a whole different technology. The dynamic variation in the new 4 sample per key piano which goes from a very soft and delicate to very bold and realistic grand piano sound. I would also like to remind those who haven't tried this to play a key as rapidly as you can and on the Yamaha P95, Korg 250 and others you can't retriger the note unless the key comes all the way up and on the PX330 it will retriger when only slightly coming back up.
The styles I would rate at about a 5 out of 10. The GM voices are for the most part fine. I have about 400 tune1000 midi files on an SD card which I demo and they all sound fine. Having the chord sequencer which you record chord sequences using the accomp. is an added plus. There is a 16 track basic sequencer as well.
Anyone wanting a keyboard with 88 graded weighted keys and very good sounds and stereo outputs and inputs for less than $1500.00 this is the best option in my opinion. I've not had any issues with build quality and have had only one bad key on dozens and dozens I've sold.
The PX3 offers better and more piano variations because this model has more options with insert effects and tone parameters which both the Casio programmers and the individual can adjust to their liking. Also the PX3 has the "ivory touch" keybed which simulates an acoustic piano for feel on the keys. It doesn't include speakers and doesn't have the auto accomp. section or sequencer. It does however still play standard midi files using SD cards and has GM voices as well. It features better midi controller functions including the ability to play 4 internal sounds (2 on each side of a split) and 4 external sounds via midi.
Bang for the buck................I rate these 2.....10's!
