Stick with the Yamaies--they'll provide you with more options, superior voices, and while they're a bit more difficult to program, the learning curve is not all that bad. The PA-80 is a good board, but you should probably take the advice of many on this forum and compare them side by side, then dig deep into your wallet.
Good Luck,
Gary
