"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've always interpreted Verizon's BroadbandAccess TOS to also mean that you can't use it to download videos from the iTunes store. TV shows run around 1/2 GB per hour episode; so if you downloaded, say, 10 episodes of the remastered Star Trek TOS you'd blow through your 5GB cap right there.
