I just picked up a new 49 inch one off Amazon UK for £721, so fingers crossed. Heavily discounted now it’s a few generations back, but still fine for a casual gamer like me.I bought mine from Ebuyer who also were selling refurbs, but those were clearly marked at a different price.
Paying a bit more I got brand new and its perfect, not even a dead or weird pixel.
I couldnt take the risk on Amazon UK, far too many bad reports, sending big expensive stuff back is a pet hate.
In another country your Amazon dealers might be different.
