Sears offers the Seiki 50" 4K2K 2160p LED LCD HD Television, model no. SE50UY04, for $759.99. Choose in-store pickup to dodge the $69.99 shipping fee. That's $70 under the lowest shipped price we could find and the second-best price we've seen for this TV, although we saw it for $38 less three days ago (since expired). It features a 3840x2160 resolution — four times that of 1080p TVs. It also has a 120Hz refresh rate, LED backlight, and three HDMI ports.

Note: No one is currently broadcasting or releasing content in this resolution ... but one day they will and you'll be ready!
