I just want this out of the hallways, so let's say $10 mostly to cover shipping in the continental US, and free for local pickup. Awesome idea - it clips to your cab and holds a mic in place - but in practice it didn't work for me for two man reasons. One, it doesn't have the range to accomodate anything longer than an Audix i5, and two, a Rectifier cab is JUST barely too long - it sort of works, but not terribly well. If you use an i5, however (and it's a great mic) and a cab less deep than a Recto, this is a pretty cool tool.
I'll also take trades if you have something sitting around you don't need that you might want to get rid of.
My cab is slightly too deep for my cabgrabber, but it does stretch a little bit further, just requires some extra force. Good bits of kit though.
