With the latest HDTV setup, you need to have HDMI cables, and when it comes to cables there seems to be a lot of snake oil.
Most Monster HDMI cables are upwards of $100 for a 6 ft. cable. Even off-brands in the big box stores seem to top $75 for HDMI cables.
Enter eBay. There are tons of different cables, most are around $20, some even cheaper. So what is the deal? Many say they are certified by some authorities which I never heard of. Others say they are 1.3a certified, etc. So, who do you trust? How much should you pay for a decent HDMI cable?
