I bought a 50 ft HDMI with, I think, AWG 22 wire. This was before HDMI 1.3 so must be HDMI 1.2, I am presently running through an ONKYO sr607 receiver to a Mits 4900c 1080p projector with this cable.
Playing PS3, DirecTV HDDVR, XBOX360 and PC at 1080p with no issues.
It was under $50 back then at Monoprice. Anywhere you can find a reasonablely priced cable with similar specs would be worth a try.
