Paulie57. I do same as you, never use a build, keep a few 'go to' reliable add-ons 2 or 3 movie only & the same for tv shows so you don't need a build to look after that number.
That leaves the sport and live tv add-ons, chop and change these as they come & go keep your cache clean using the Ares wizard and a cheap box does the job if you aren't a gamer.
I said elsewhere my Qbox (£40) has been flawless for 14 months if you want to upgrade get a Minix or chance a Mecool, H96+ or Yoka. I say chance cos if you get a good one you're laughing (half price better specs than a minix) but you can get a dud. As for Beelink, they get good reviews on youtube but one look on their forum puts me off.
Treat it as a hobby, I do, as most on here were scrambling for S*y BO last night I watched the boxing perfect on Showtime :)
