I am looking to put a tv out in my garage but I have a couple of obstacles. First one is the garage isn't heated or cooled and here in southern Missouri we have a full range of 0-100 degrees depending on the season. I am in the process of installing a heater in the garage but it would only be for when I was out there and not continuous since the garage isn't insulated and the garage will never be cooled besides whatever the outside temp is. I need a tv probably around 50" or so and it looks like plasma is probably the cheapest way to go. I am also trying to keep the price around $800 bucks. I see Wal-Mart has one in my price range and I thought about going that route and purchasing the extended warranty, that way if anything happens I am covered. Anybody have any similar experiences with something like this or have any recommendations as to what else to look for? Thanks in advance
