I got the chance to play the wk3500 the other day. I had tried the 3000 before and wasn't sold on it, and I think the two are supposed to sound the same, but I will say that I was pretty impressed with the 3500.

I haven't tried the dg202, but I have played other Yamaha boards in the 3500's range, and I would agree with George here. I think the 3500's piano sounds better ( to me ) than any of the comparable Yamaha boards.
