I difer from Ilija. I own a PSR-740, and it is not a $500 keyboard but a $1100 keyboard. It has hundreds of very realistic and great sounding tones (many are the same as the PSR 9000) including drawbar organ sounds. It has 160 styles most of which are very very good. It has two intros, four style variations with drum fills, and two endings. It's got one touch memory and sampling pads, a decent vocalizer, modulation and bend wheels, a very large lcd display and many other goodies. One other great feature is that the buttons are well placed. It is also very light to carry around. Disadvantages are that it doesn't play very loud, it is very difficult to play additional styles in a live setting, and the one touch settings cannot be edited. But for a little over $1000, I don't think there's anything as good. At the very least, I think it's the only keyboard with a vocalizer in that price range.
