I play a 9000 Pro fairly often, as it belongs to a good buddy (Glen Campbell's former piano player) who lives about a half hour from my place.

It still sounds very good (especially the piano), although, he also has a Tyros3 that he likes a bit more than the 9Kpro. He keeps the latter because of the great feeling 76-note keyboard (he is a piano player after all)

The PSR-9000 (with the on-board speakers) is pretty heavy, and the 9000 Pro is about the same...they have their own distinctive CD like Yamaha sound, but the SA/SA2 and mega voices in the Tyros models (especially the T4) really make the instruments come alive.

There are quite a few 9000's still in use, according to my client list...mostly home use.
