"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!"
Excellent, it's only the beginning of the incentives hinted at by the Insiders over at Blu-Ray.com to try to get DVD fence sitters to switch. I guess you'll soon enough be able to buy a Bogo title (which brings down the price per disc at about $10-$15), and still get one of the two discs free with a $10 coupon, for an effective final $5-$10 per disc.
