I got a SANUS BLF328 mount for my 75 inch TV (
https://www.sanus.com/en_CA/products/tv-mounts/blf328/) and have really enjoyed it. It's sturdy and has a great range of motion - without it, I'd have a hell of a time getting behind my TV to swap inputs.
I paid $200 for mine (negotiated with best buy when I got my TV), but it's a whopping $440 now!
