P.S.
Sound IS important, but as a live player ... comfort and versitility is MORE important to me. I've said before that I can entertain any crowd with a good bass and drum, and ANY old piano type sound. The better sounds "enhance" the performance, but they do not "make" the performance. That's what I get paid to do.
I'd love to have all those terific Ketron sounds (with 128 note polyphony) and styles with the button layout of the Yamaha 9000pro, and the size and speakers of the psr2000..... or SOMEthing like that.
