I can +1 Sceptre. I got a Sceptre 65" 4k dumb TV on sale for $320 last year and have been happy with it. I hope I never have to join a smart TV; my experiences with them have been almost universally bad.
I got a perfectly adequate 60in two years ago from Walmart’s Black Friday sale for around 200 dollars with in store pick up. I’d guess you’d be able to do something similar this year
