USB Condenser Microphone

Has anyone tried to use USB condenser mic?
Something like that one.
I want to record my music but I don't wont to buy lots of equip to make a studio.
What can you say? Is it worth buying?

Well... it seems that no one knows if it's good or not.
Finally I've taken another one USB condenser mic. That one.
It will arrive in 2-3 weeks. And I will record my guitar playing and will share my experience, and maybe will post my music in Listening Post :)
