Jakester... the main issue is... getting the internet speed at a great price. For example... if you have 2 solid internet providers in your area that run promotions for 6 month or a year... you could switch back and forth and save even more money. If you have only one internet provider... to get the speeds you need you could end up spending $50-$60 on internet alone.
I tried Kodi back in 2017... used Amazon Fire Box (not stick) and a lot of movies were buffering constantly. I know a lot of things have changed since then.... but I only pay $62.00 a month for DirecTV... not ready to change yet. But again... I think the main focus is... internet price and speed. Then you can study other things...
