yeah I got a bit lazy there, at 55 inches you are at $604

When you go to 65 though its $1004 so pretty big jump.

Oddly enough going from 65 to 75 is only another ~375 USD (1377)

To me the best deal seems like 50 or 55 inches, although your room size and seating positions are likely the most important.

Also interesting if you're in the USA Best Buy does have some non-smart TVs and even a filter for it, although its mostly no-name brands or Samsung.
