my kind of thread! of course, it won't top double digits in replies.
tigers, i usually go to the house of musical traditions every few months to pick up a gong or tibetal bells and bowls, shakers, etc. chuck levin's has a bunch of cool shit, too. the guitar centers round here are weak, but they do have some basic stuff.
i'm a big fan of playing found objects, and if you're creative and resourceful, you can figure out a way to generate sound out of almost anything. one of my favorite recent tricks is rollong beads on my snare and cymbals, especially when they're attached to contact mics.
