I demoed the Casio WK3500 last night and this is my $0.02 worth:
The acc. piano is good but a little bright for my taste. The organs are very good and lots of them, but I think it is mainly because of the excellent leslie simm. The sax's (not sex's) were good but not mind blowing. The strings are unuseable as well as the flute voice.
The styles were busy and many had wild synth leads in them, that are inappropriate,IMO, for POP or ballad styles. This style is great for house and trance, but I don't even like it for rock. It's probably something that a youth would like, and I'm not a youth. They key feel was very good.
Would I sell my PSR550 to get a Casio? No. The PSR550 has better styles, the sweet voices, and more support. The Casio has great value for the money and is a direct competitor to the PSR550. This may influence Yamaha to improve their organ voices (especially the DSP), include more user slots for styles (only 3 versus 16 on the Casio), possibly include an SD slot and improve the key feel. Should prove promising for the next PSR560 or PSR600.
P.S. There is no way this is a competitor to the PSR2100.
