A good drum/percussion program?

Just wondering if anyone knows of a good quality drum program, preferably free, that a buddy of mine could use. I've looked around, but not too much luck, and I don't want to sit through every program trying to find a good one that has the crisp and realistic sound he's looking for, instead of some craptastic midi sounding one.

Any and all help will be gratuitously thanked!

Wiggles, dude, if that little flash drum machine is just a sample of what Acoustica can pull off, I'm impressed already! Any chance it plays rock drum setups as well?
