Being a bit of a luddite, I have not been in this arena before. But thanks to some impressive labor day sales, I replave TWO televisions today, you know...weighs 120 pounds, 4 feet deep...etc. With a slick 46 from Sony and a 42 from Samsung. Both LED-LCD types. Pictures are incredible. Anyway, on one, I feed my cable straight to a tuner-equipped DVD player, so decided to use an HDMI cable to go from there to the TV. Sp tje question: is there really a significant difference between an HDMI cable that is $19 and one that is $89 ?? yikes!!!!! I am talking 6' length in both cases.
