Podcasting doesn't require sophisticated or expensive microphones for recording. Simple USB microphones will do quite well. One that comes highly recommended is the Plantronics DSP 400. It is a portable headset that provides nice recording quality. If you want to go a little higher end and give your voice a little "richer" more dynamic quality, you might want to look at Snowball Mic from Blue.
