I used to have a psr 2000 and recently bought the s700 it also has all the cool, live and sweet voices. It cost me less, Brand new, than a used psr 3000, I used to have the 3000 also.

I also bought a TC helicon harmony m for the vocals and still spent less than a used s900.

Of course I don't have the SA voices though. But obviously I don't care about the SA voices because I use mine mainly for backing tracks.
