1-1/8" Greenlee Knockout Punch I can borrow?

Does anyone have a 1-1/8" Greenlee (or similar good quality) knockout punch I can borrow to punch a hole in my firewall for a passthru? I will pay postage both ways.
Thanks!
 
I used a hole saw.

Trevor, I couldn't find one either and bought the proper size hole saw from the aviation department at Lowes. Boelubed it up, clamped a 2x8 in the inside and drilled/cut away. Not perfect, but there wasn't a whole lot of cleanup to the hole. YMMV
