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 agree with Joshua. I have a over 100 programs in my instant queue, and I'm very happy with the instant streaming as it is today. I see it as an added "bounus" which supplements the material that I receive on DVD. For newer releases, I'm usually more concerned about picture/sound quality, so I prefer to get those on DVD. The lack of newer releases available via streaming doesn't bother me.
