i have never owned any flat screen or had an hdtv before. buying a samsung 50" plasma, i have time warner cable with the digital cable box in the family room with the basic HD package. time warner gave me some grey (what looks like but not sure) component wires for 'when i upgrade my tv' the installer said. i have heard best buy / circuit city, etc charge an arm and a leg for hdmi cables and to NOT buy them from the chain stores. what will i need to my tv hooked up? will the grey cords my twc guy gave me work, or should i buy something else/better, like on eaby? i just want to have everything ready to go when i make my purchase and looking for some guidance, thanks!
