Dave,

I don't remember the PSR9000 having improved drums over the 9000 Pro. Then again it wouldn't matter much because I think that all Yamaha's arranger drum sounds are weak, even on the newer arrangers like the Tyros 3. Definitely an area that needs some serious improvement.

Drum sounds aside the 9000 Pro was a fantastic concept that would have sold well were it not for the slow CPU and lack of software improvements on Yamaha's part. Still for $800 the purchase is a no brainer. Chances are if the original poster waits he won't have to make a purchase decision anyway, someone else would have snapped it up before him.
