"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.

Russia extends into Asia. So when you're talking about Russia it's not just Europe your talking about.
