I recorded my Sept 15 audioblog before hearing Adam Curry’s from the same day. Synchronistically, we were both talking about Radio Shack microphones. He was talking about the cheapish mikes that sound OK for the price. The ones I am using are the same ones I used for my radio show, the PRO 3004 models. You probably don’t want to record your next album with these, but for the audioblog and even the radio show they sounded plenty good enough and are only $40 apiece. I’ve been happy with mine.
