Bit the bullet on this one last night for this price, Warehouse currently have this 58" 4K UHDTV down to $499 ($400 off they say). They also have Free Shipping on this one at the moment, so delivered to your door.
Used the Warehouse app with the Wish Foundation vouchers that show up in the app in your "wallet" and saved another 0.5% lol ($5 off $50 coupon) ..
3 years warranty as well. Older reviews say these have been good for the price after some tweaking of picture settings etc.
Hope this is useful to someone!
