Yeah, I agree with Scott here.  Spend some more time on it.  To really see if this boards for you, it will take hours, and days  

  If you're looking for the "piano" feel and got the PSR-3000 at a good price, consider buying a low cost 88 key controller or even digital as an add on.  Possibly Casio 100/310, Yamaha P-60/70.  You can midi them up to the PSR-3000.
