My setup:
Grande Cable Internet 300/gb ~$49/mo
PSVue ~$50/mo (most sports channels for the price)
Netflix whatever they are charging today.
Prime Video (sunk cost would have prime anyway)
Hardware
Main TV -- Apple TV 4k
Mancave TV -- Roku Streaming Stick +
Bedroom TV -- Roku Streaming Stick +
Patio TV -- Roku Streaming Stick +
To get local channels Tablo Dual Lite plus cheap inside antenna.
There is nothing I want to watch that I can't watch.
Total Opex for 4 TV's ~ $125/mo (includes $45/year for Tablo schedule service) you could argue its only about $60 since I was going to have that same internet connection anyway.
Capex
Apple TV 4k 64gb $199.
Roku Streaming Stick + 3@$59 each = $177
Tablo Dual Lite = $149
Antenna = $30
Total Capex = $555
Going with all Rokus would obviously save money, we're all in on Apple and the Apple TV serves as our Apple home hub. Roku is a really solid product that supports everything you've ever heard of except Apple stuff. I find that usually the streaming services don't offer one or two local network channels, which one(s) vary from service to service. Likely over time they will all support all the local channels. If you're good with that you could cut out the Tablo. You could also cut that out if you were ok with not streaming the local channels to every TV and wanted to hook up the antenna to just one.
With the capex amortized over 2 years I am saving over $140 on my cable bill.
This is, however, no panacea. Streaming, while very good still suffers glitches and sporting events are delayed about 30 seconds or so. Also prices are rising and eventually streaming will be as expensive as cable. Then we'll have to look for something else.
