BuyDig offers the Sony 65" XBR 4K Ultra 2160p 3D WiFi LED LCD Ultra HD Television, model no. XBR-65X850A, for $3,298. At final checkout, the price drops to $2,749. With free shipping, that's tied with last week's mention as the least expensive Sony 65" 4K TV we've seen. (It's also the lowest total price we could find for the TV in sufficient stock by $201.) The HDTV features a 3840x2160 resolution (four times that of 1080p TVs), 120Hz refresh rate, edge-lit LED backlight, WiFi, USB, iOS and Android controls, and four HDMI inputs; it includes four pairs of 3D glasses.
