What Bacus said. A few good choices are out there.
. I went all out and got the FP90. Wow! I'm loving it.
My second choice was the Casio 360. I have recently had a chance to play the FP 30 and while not on the same level as the 90 it's very nice.
Seems there's a few,choices in the under $1000 range that are nice. Then the big jump up to the TOTL units.
BTW the 90 is heavy but not as bad as I thought it would be to move. I'm going to get the Roland case for it and if I get lucky I can find the right job where I can just play and sing thru it's speakers and need no amp.
