They cost about as much as a high end 1080p set now. Some are even under $1000. A few years ago these things were $4000+ If I didn't already have so many HD sets I'd cop a 4K one for the hell of it but I would need to sell one of my 1080p sets first and TV sets are worthless on resell value.
You wouldn't have much use for it right now tho, you got 4K movies downloaded my nig?
And supposedly these TV's dont have the newer HDMI standards which will be mandatory to accurately stream 4K content (or so I've heard)
But, I seen them for as low as 700 on slickdeals. I can post up the deals for you if you really interested.
Might not be valid anymore, but they go on sale every month. black Friday right around the corner too
Expect them to be plentiful in the coming weeks
