Blue jeans cable is another good source for HDMI cables. There is also a wealth of info on their website, much of it debunking the myths surrounding "high end" cables including Monster.
Blue Jeans cable also has a low price line, Tartan Cable, and I've used the Tartan 28AWG HDMI cables with great success (apologies to Borat).
I have not used the Tartan cables for anything over 10 ft, however. For longer runs I use the Blue Jeans cable. Both will pass 1080p signals just fine.
The tartan cables are a little more expensive than the monoprice ones, but for some reason I trust the Blue Jeans Cable folks a little more...
