Squeak_D,
Have you tried the Casio WK3500 yet? It looks like it could be a serious challenger to the PSR550. It has 76 full size keys. Instead of buying a controller, you could just replace the PSR550. You might not be interested because it only has a 6 track recorder. I will try to demo one tomorrow.
