Guy at church owns an electronic store in town. Got to talking to him about my recent plasma problems. He said that the TV's that walmart sells, like Samsung, Sony, etc. etc. are not really the manufacturer, but walmart. He told me that if he sold me a TV, it would be way better than walmart and last ten times longer, of course his prices are way up there. But I got to thinking, is there a difference between what you'd get at walmart as opposed to going to a non-chain type of electronic store?
