A handful of experts have written about how cheap HDMI cables can be just as good as expensive ones. That’s true. And if you're going to go cheap, the Monoprice High Speed HDMI cable with Ethernet is the one to get.
It’s less than $10 for a 6-foot cable, it has a lifetime warranty, and it's rated to handle next-generation signals beyond today’s high definition. You can tell by reading the specification pages that Monoprice takes its cheap cable performance seriously, because they go to the trouble of rating them for data throughput, something other cheapo cable makers don't do. Most telling, however, is the fact that editors at CNET not only use them in their test labs when putting home theater gear through their paces, some even use them at home.
You can get a cable from Monoprice without the separate ethernet channel, too. You probably don’t need the ethernet standard in your living room today — none of the midrange surround-sound receivers I’m recommending utilize the tech — but when future proofing costs 4 bucks, I say do it.
