I just picked this up two days ago:

If you are looking for a large condenser microphone, this baby has been reduced beyond belief. This mic origianlly went for close to $300 USD. American Musical has them for $59/69 with/without shock mount. This thing picks up even the subtlest nuance. I own a Shure Beta 57a and this is equally as awesome in a different way. Check out the specs on it and maybe it meets your needs. For the price you cannot go wrong.
