Well, here's how I'll answer that since I try to refrain from brand recommendations and websites. (Forum members are encouraged to jump in with their opinions as well).
For the price savvy, I've heard of really inexpensive HDMI cables available at Monoprice.com. I can't speak for their products, services, or customer service, but some forum members can.
Monster is probably the biggest brand name out there. To their credit, I believe they have a lifetime warranty on their cables. So if it splits internally or the dog chews it, or the kids play jumprope with it, I believe the policy is that you get a new one. Again, can't speak for that officially, just my personal experience.
Some of the reported marketing that has come up in the forums is 120Hz cables. It's a little misleading, since there is no 120Hz signal being passed from any source. There is 1080p, yes, but not 120Hz. It's all 60Hz, and the television will upconvert 60Hz to 120Hz after it passes through the cable. So save some money and avoid the "120Hz cables". At this time, it's my opinion that it's an unnecessary upgrade.
Most cables will work. HDMI will either pass data, pass it intermittently, or it won't. Some users swear that it doesn't matter which cable you get, some swear that some issue (blinking, flashes, game play, drop outs, etc) disappear when they buy a more expensive cable.
So if I'm a budget-minded consumer, I'd start inexpensive, and work up if necessary. Hey, we're all trying to save a few dollars, right?
