I don't know if you tried this place, but I've always been amazed at the amount of free sounds they have.

A normal wav file can be made into a loop (although sometimes it takes a bit of editing to get the beginning and end points right), and used in BIAB.

Hopefully this helps (sorry it is too late for Christmas though). frown

EDIT : I see somebody already edited one for looping on that page I posted.
