OK- my concern is that any mic sensitive enough to pick you up throughout the room will also bleed a lot of ambient noise into the tracking cans. But what the hell- shell out the big bucks and buy a Behringer ECM8000. $36 new, omnidirectional, more than sensitive enough to do the job. Be aware that they will also pick up your monitors and send them straight to the tracking cans, which I believe will generally suck.-Richie
