Scottyee:
Let me add one other cool and underlooked feature of the PSR2000 for you: it is one of the first to implement the new XF Scorch file format that allows it to display scrolling sheet music, which is utterly useful and something the 9000 series does not do (yet?). It'll likely be in the new Tyros series I'm guessing.
I can't get over the 64-note polyphony limitation of the PSR2000 though... frankly, to perform the way I do would require me to own not less than two of them and even then I wouldn't have the polyphony of my expanded 9Kpro. In fact, I was using a Kurzweil PC88 and a Roland EM-2000 on stage for performance and I replaced both of them with my 9000 Pro.
