Jimbo, I have bought 6 buck 6ft HDMI cables on the Internet, and a 70 dollar monster cable HDMI cable. I have a 40 inch Sony Bravia, ane when I first installed it 3 years ago, I tried both cables and could see absolutely no diffence in picture quality, The expensive cable was better looking itself, and seemed physically sturdier, but picture quality? these eyes could see no difference and I have fiber optic service to the house from Verizon FIOS. I returned the expensive cable for a refund. And as Terry said, its all about profit!
