Cleokatrah, I know people will dump on me for saying this, but I bought 2 tiny clip on mics from Radio Shack, the little tie/lapel mics. they are omnis and sound decent. i have a mule and a Doc watson show with them. no pre amp just them running into a D8 If you would like copies, PM me. I can also email you some pix of how i rigged them up (clipped on my glasses).
Granted thes are not high end mics, but my banged up hearing likes the shows they made and they are reasonable. I want to sneak them into a symphony.
Good luck.
