If you're talking about new flat screens, you will either have to go with one of the "no name" brands or a really small (19"-24") tv of a good brand. The top of the line are Samsung and Sony, but LG, Panasonic, Vizio, Toshiba, ect. are all good brands.
Some High Definition TVs that have good picture quality and other features include Vizio M320SL, Toshiba 32C12OU, Vizio E320i-A0 and Samsung PNE450 series. You can get these HDTVs for $300.00 in most stores.
