I sold the PA80 and bought PSR2000 because of the ease of operation. The PA80 did sound great to me, maybe better than the 2000, but it was too difficult to operate in live situations. I didn't like the lack of fills, intros and endings, and the vocal harmonizer is "primitive". Bear in mind I don't use many midis. I play almost everything live, using the styles.
They are both great keyboards and the PA80 is certainly of hardier construction.
