I just got a catalog from Crazy Crow Trading Post.
Go to Native American Indian Craft Supplies- Indian Craft Supply- Buckskinner Supply
and look up "Drums and Drum Frames".
I think this will expand your horizons.
There you will find:
Sweat Lodge Drums and
Pueblo Style Drums
As you stated within your thread, Not Christian Drums.
You may also be interested in purchasing the 500 Nations Soundtrack Audio CD by Peter Buffet also know for his orchestrations.
It's quite invigorating.
Some hand drums from India are also quite fascinating.
