Is there a difference between expensive hdmi cables and cheap ones? I have a ps3 and I want an hdmi cable for the best picture. Now Sony has official hdmi cables for $60.00 but I've found hdmi cables on Ebay for $2.00-15.00. I know the Sony cables work because it says Sony but I don't know about the other cables. Do they offer the same performance or are the ones on ebay just a scam?
