Bill,
A PSR3000 would be perfect because you could copy and paste all of your styles you use on a floppy and copy them to the PSR3000 either by using the smart media card or just transfering the styles through USB.
You would have all the great Tyros sounds and styles and song playback features but would only have to spend $1400.00 dollars.
