My music is all instrumental, and I fell in live with the SA voices on the Tyros2, but I still wanted to keep the portability and built in speakers of my 3 year old PSR-3000.

So, I made the upgrade to the S900...absolutely no regrets...the SA Sax and SA Concert Guitar were voices I did not want to be without.

Also, the S900's audio to USB recording is something I use a lot as well.

If right hand voices aren't a primary concern, stick with the PSR-3000.
