Does anyone have one of these that I can borrow? Preferable around NWI, but if we can flat rate ship it I'd be willing to pay the $10 round trip. If you have a bit of compound (220 should do) that would be a great bonus. Looking to square up a couple of receivers in my safe, but don't think I need my own.
