Hey guys, I'm new to the forum. I need some advice on HDTVs, if you know anything. First of all, I don't know the difference between 720, 1080pi, whatever. And I'm not sure if cost makes a difference. They have some great-looking models at Costco that are pretty affordable to my budget, but I don't want the thing to konk out after six months of use. I know I can always return it but those things are heavy!! Is it worth it to shell out the big bucks for a name brand?
