I've read quite a few posts here at SatGuys about buying HDMI cables from Monoprice as opposed to some of the large electronics box stores or buying Monster Cables. Monoprice cables are as good as if not better, etc. My question is this... what is the difference in quality of the HDMI cables available at Monoprice? They may have several 6' HDMI cables at different prices. So is the 35.00 one better than the 10.00 one? How do you know which one you need?
