I bought a "premium" Roku box brand new for I believe $90 so I could have one with an ethernet cable. That was 3 years ago and it's currently supremely buggy. It goes green, black, crashes mid episode, if I skip a few times within a few seconds the audio might desync. It was already bad but I got a new speaker system and hooked it up to an AV receiver and it instantly got several times worse. I don't know if my experience is typical but 3 years is a disappointing lifetime for something like this IMO.
