Over on Geekazine, I brought in a comparison of the ATR2100 and ATR2500 microphones from Audio-Technica. These are sub-$100 microphones you can use on your podcast. They both connect to a PC or iPad for use with Bossjock, Garageband or another podcasting app.
The full video review is below. Which microphone do you use? Will you switch? Let me know!
