I'm very happy with my PSR-S900...inexpensive, great OS, superb SA and Mega sounds(exclusive to Yamaha) and very light and portable....nice responsive action, too.

And Donny, you're right...the investment to profit ratio is better than any other arranger, and if you're in this business to make good money and still have excellent performance from a keyboard, you can't go wrong with the S900.

Best "bang for the buck" of any arranger.

But one hardly needs my opinion on the matter. The market has spoken loud and clear...S900 rules big time!
