There are some still out there (in Australia - YMMV). I just bought this on Wednesday: http://www.bauhn.com.au/product-listing/58-4k-ultra-hd-tv-AT...
They're good with warranty returns, but usually can't give you a replacement product due to how they do batch/bulk sales and don't keep recurring stock, so you generally end up with a refund and have to start shopping around again for an equivalent product.
