Larry, I talked with Don Mason about the SX-900 and he said it is an outstanding keyboard and sounds much better than the S-950 and S-975. Most of the other reports I've read thus far on the PSR Tutorial site pretty much say the same thing.

I would purchase one in a heartbeat, however, that's just one more thing my children would have to sell upon my death - I don't want to leave them or my wife with any burdens upon my passing.

Good luck,
