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!"
It's interesting that Mark Cuban continues to add content to HDNet. Will both of these high-profile offerings expand the base for the network? Right now I am unable to receive the channel on Comcast, as they have their own HD offerings. Perhaps this will increase it to a level that it will be available to more people. I would hope that the base is expanded because I would like to watch it at some point.
