BTW - I used to own a PA 800 as well...
I havent touched a PA 900 but cant imagine why it wouldnt please you more than the 800?? surely its a step up?

then again.. nothing beats the keybed feel of the PA3x... its another league from the PSR & PA800/900 series. I even prefer it over the FSX keybed on the tyros / Motif line.
