3 days ago just got the 70" P-Series Vizio, 4K set. Stunning.
$500 off at Coscto right now, only $2K plus tax. a steal for the performance of it.
it was $2500 before Christmas, on and off, Costco sells out of the fast when they get them.

to match it in the Samsung line (which is my baseline like a 7150 or 8000 series) or a Sony, you have to almost double that price = $3500-4K
I don't like the curved sets, they have a glossy finish and have more reflections, the P-Series in Vizio has a nice satin matte finish.
the 4K upconversion from ABC/NBC/ESPN, or streaming native 4K off you-tube is amazing.
