I'm Chime in what is working for us.
Hardware:
Powered HD Antenna - Goverment gave to me free years ago during the switch over.
Playstion 4 - $300 (can find for $200 now.) Can play numerous streaming services including ESPN (but not BTN, I have to hook laptop to TV for that), as well as Plex (I've digitized our DVD collection onto a Harddrive and with Plex can access it anywhere.)
Services:
WOW! Internet - $42
Netflix - $11
Amazon Prime - $9
Shady:
In laws drop $200 a month for all their bundled packages and don't use their online log in. So we use it to stream mostly ESPN, BTN, and Disney.
Total - $62
I'm a little bummed that I'm over $50 a month, which is what we set aside in our initial budget, so I'm on the look out for another ISP to get the Interent service fee lowered.
