Suggest a mic?

[chall]

Hello, I have an iRiver. Wondered if anyone could suggest an inexpensive, but good quality mic.

I just discovered podcasting a few weeks ago. I heard a new podcast by Dash Rip Rock. If you know the group (rock-n-roll, punk rock), you'll love the original material (unrecorded) they share, plus spontaneous stories and songs. www.freewebtown.com/dashpodcast.
