Let the hive mind of Engadget get that for you.
"I've found myself using my PC for a lot of conversations lately, and I'm also considering recording a podcast to share with anyone who will listen. There are tons of USB headset / microphones out there, and I'm hoping someone has some solid recommendations based on experience. I'll consider both headsets and standalone mics, by the way, but I'd like to keep the bill under $100 if possible. Help!"
I'll be making the switch from HTC (for the 614c); I'm sold.
Also I believe these will both be QUAD-band.
Numeric keypad clinches the deal for me (I don't dial numbers alphabetically)
Just as soon as these come out in europe...
