I remember seeing the cheapest 70-inch 1080p sets go for over two grand just a few years ago. Now with higher resolution panel prices dropping, you can get TVs like this 70" RCA 4K Smart set for just over half a grand without coupons to enter or rebates to mail. The Smart functionality of this set includes a fairly minimal array of streaming services, but you can always bring the price up to $600 and add a Roku or similar to get everything you'd ever want.
