Fran, I think you'll love the VR-760 especially if you like to play Organ. The Organs on the VR-760 are superb imo. The Piano patch's are pretty good too. As are the Electric Pianos. The VR-760 has 128 note Polyphony and it even has a basic rhythm accompaniment feature although it is not an Arranger. Plus it has 76 Keys. The Drawbar Sliders and all those other buttons and knobs make it a real hands on Keyboard.
PS: Sorry to hear the PSR 2100 didn't do it for you. But there are plenty of other "toys", (no pun intended)

out there to choose from.
Best regards,
Mike
