Francis, I've owned a Yamaha PSR-3000 for 12-years. After all those years, I decided it was time to move up and get a PSR-s970, which has vast improvements over my older PSR.; but that model is having problems with the buttons -- as you can read on the PSR website forum. So I put it on hold, and got my PX-560 because it has 88-weighted keys, and is billed as a stage piano not an arranger. Therefore, not burning bridges nor duplicating efforts by having two similar products.     However
