Walmart offers the Sharp Aquos 43" 4K LED-Backlit LCD Ultra HD Smart Television, model no. LC-43UB30U, for $449.99 with free shipping. (Best Buy via eBay has it for the same price.) That's $148 under our mention from October (which included a $200 Dell gift card) and the best outright price we've seen. (It's also a current low by $100.) It features a native resolution of 3840x2160 (four times 1080p), a quad-core processor, streaming media apps (including Netflix, YouTube, and Vudu), iOS and Android control apps, MHL, 802.11n wireless, and four HDMI inputs.
