I have an XP-30 and I think it's great! I'm not saying this because I have one, but because I think it's a great deal, and overall, it sounds better than most of they other synths I've played. If you're looking for piano sounds, there are tons of them. In the banks: USER, PR-A, XP-A (Session), and even in XP-B (orchestral)! There are quite a few organs too. I like most of the solo Saxex, but I wasn't too impressed with the solo trumpet patches. But I'm sure they can be re-programmed to sound better. There's so much stuff in this thing I can't think of all of it. If you would like any specific info just let me know.
