I actually have a WK3200, which is nearly the same as the WK3500. There is very little not to like on this keyboard and a whole lot to like. In fact, Casio has taken a step backwards in the models that followed. The sampler on this is superb (better than anything Casio has now). The analog synth capability exceeds what the new semi-pro keyboards have now as well. The organ, piano, e-piano, guitar, and woodwind sounds (including the saxophones) are amazing!! As for everyone's issue with the keyboard, I found a fix for that: wheel weights (that I stuck under each key to give it a semi-weighted feel) and white lithium grease (applied generously under each key and to the plastic piece it fits into). Do that and the feel equals keyboards costing $1000 more!!! Oh...and that whole modification cost me $20.
