Walmart offers the refurbished Vizio 50" 120Hz 1080p WiFi LED-Backlit LCD HD Television, model no. E500I-A1, for $399 with free shipping. That's the lowest total price we could find for a refurb by $60, although we saw it for a buck less in April. (It's also $275 under the best price we could find for a new model.) It features a 1920x1080 (1080p) native resolution, LED backlight, WiFi, Ethernet, USB, VIZIO Internet Apps (with Netflix, Skype, Hulu Plus, and more), and four HDMI inputs.
