For my birthday which is Tuesday, my wife bought me the Behringer Podcast Kit and I decided to take it for a spin. It comes with a high quality microphone, headphones and a Xenyx 502 Mixer with Mic preamp. After tweaking Windows Vista for about an hour (My control panel kept crashing, turned out to be a bad .cpl file in my \windows\system32 directory). I was able to get my USB mic configured and setup, then it took another 1/2 hour fiddling with Audacity to get it to recognize and use the mic.
Here was my test podcast using this new birthday gift, I intend to use it to make more screencast training demonstrations and post them on YouTube and in my blogs.
