Walmart offers the refurbished Vizio 50" 1080p LCD HD Television, model no. E500AR, for $429 with free shipping. That's the lowest total price we could find by $170, although we saw it with pickup for $30 less in July. It features a 1920x1080 (1080p) native resolution, USB, and three HDMI inputs.

A 90-day warranty applies, but it's unclear who backs it.
