so, what should i get? i have been looking at the MECOOL ATV KM3, mostly becaus it seems to be cheap and pretty powerfull from what i can tell? but i cant find anything about it supporting hdmi-cec i really only want one remote. and what is the diffrence between the km3 and km9 pro?

i have also been looking at the Formula Z8 Pro 4K, its a little more expensive though, then there is also the gtv version?

the nvidia shield pro is to expensive, and it needs to be a small box, i can hide behind my tv, as its mounted on a wall without anything to put a box on, so it needs to be something i can hide away.

so what box should i get? i prefere to get something that runs fast and no lag in menus and so on.
