what kind of sound are you going for?
rocking punchy- used AT atm25
full, jazzy- used cad e100
if you want to buy new, i had a K&K BO7 for a while, pretty decent mic. made by germans living on the oregon coast. they sell them on ebay for around $100. nice little pseudo shock mount. they are really nice people. the BO7 has a lot of top end so it has a more "modern sound" (more modern than i liked). WHOA, i take it back. now they are $200! ok nevermind.
