iRig Mig for Youth Group?

[Ron M]

I want to record some of the songs we're doing in our youth ministry.
I've seen iRig Mic and VocaLive are available for the iPhone.

http://www.ikmultimedia.com/irigmic says it's a condenser mic!
This looks like it would be perfect for bringing with me on Wednesday nights.
Is anyone using this yet?
