What is a good computer microphone that you'd recommend. I'm not talking about a headset. I'm referring to a regular boom mic (w/ a clip or stand) that plugs into the sound card. The I currently have (Labtec AM-222) is over 10 years old and is begging to be replaced. I'd like to keep it under $20. I see MonoPrice.com has 2 of them in that price range, but only 1 review total between them. TIA.
