Walmart offers the refurbished Vizio 42" 1080p LED-Backlit LCD HD Television, model no. E420-A0, for $298 with free shipping. That's tied with our mention of a refurb from December as one of the least expensive 42" 1080p LED LCD HDTVs we've ever seen. (It's also $104 under the price of a new unit.) Features include a 1920x1080 (1080p) native resolution, LED backlight, USB, and two HDMI inputs.
