Walmart offers the Hitachi 55" 120Hz 1080p LED-Backlit LCD HD Television, model no. LE55G508, for $449.99 with free shipping. That's $10 under last week's mention, $99 off list, and the lowest total price we've seen for this model. It features a native resolution of 1920x1080 (1080p), 120Hz refresh rate, USB, and three HDMI inputs.

Note: The headline on the product page states this is a 60Hz HDTV, although the detailed specs state the refresh rate is 120Hz.
