CoasterTim,
Personally I have no use for the PSR3000 but it is a great keyboard for the price, but I am well seasoned with the use of the PA-50 (previously I owned the PA-80 which is almost identical) and I can assure you that is a superb keyboard , a complete knock-out for the price and ever so complementary to the use of a Yamaha PSR-3000. A combination that could last for many years in my opinion.
Having programmed very extensively on this board over the last few years I disagree with Ricok's remarks about the styles, but obviously that is a matter of taste. Should you decide to purchase one, just drop me a line and I will be glad to provide with you all sorts of new software.
regards,
