Well,
Here are my 2 cents,
I think the PA80 is the best choice here.
It has the best sounds and styles.
I've played the PSR-2000 and found it rather a disappointment, The styles sound a bit keyboardish and unrealistic, so do the sounds.
But every one has his own taste.
My personal favorite is the Ketron XD9, which has the best sounds and styles IMO.
I've compared it to the other two (PA-80 & PSR-2000), I think the XD9 is the best, the PA80 second, and the PSR-2000 third.
I've also heard the VA7 which sounds pretty impressive too.

Good luck & Greetz ,
Marcel
