Please Help!

Ok so I’m new to this kodi and want to stream from now on instead of paying a lot of cash to sky every month, first thing first, i want to buy a android tv box that i can install kodi into or already has it installed that supports 4k hd tv. i really want the best one for quick and effective streaming hence why i have a budget of £110 for this. I want you guys opinions of the best box i can get for this price as there is just too much options and I’m not really sure which is the best for me.
