Here are a few that work fine.
HammerHead
Hot Stepper
Over on the Kristal Forum a lot of us use this one.....
Leaf Drums
And add the drum sounds from here.....
ns_kit FREE
Its a large download, but well worth it. Stop by the Kristal Audio Engine forums and give a listen to some of the music from Dino to hear the drums in action.
Hope this helps!
