Blue's original Yeti microphone is one of my favorite podcasting mics, and MacMall has it on a killer deal this week for just $79.99. This microphone connects to your Mac or PC via USB, has on-mic adjustable gain control, passthrough (and zero-latency monitoring) headphone jack with separate volume, and a mute switch. Additionally, this mic has multiple elements, and you can configure it in stereo (interview) mode, cardiod mode (for single-person podcasts), or omni-directional mode to pick up a whole room's worth of people. Check it out, it won't stay at this price for long.
