Ordered the Panny S97S today to hook to my HDMI 53 inch panny RP TV. Q: What is with HDMI cables being so priced different? I can get one on ebay for 20 bucks. Or there are ones that say "Super High Resolution" cables for 60 bucks and up. I think the $20 one will do just fine, right? I guess my question is, could any of you tell me if you've noticed a difference with different cables or is this a waist of money?
