Walmart offers the Naxa 24" 1080p LED LCD HD Television with DVD/Media Player and Car Package, model no. NTD-2457A, for $139.88 with free shipping. (Fry's and Brandsmart USA charge the same price; so does Amazon, although it's currently backordered.) That's the lowest price we could find by $47. It features a 1920x1080 (1080p) native resolution, LED backlight, DVD player, DC car adapter, and USB and HDMI inputs.

Note that at Brandsmart USA, you'll need to search "NTD-2457A" to find the deal.
