So I would go with a high-speed cable provider (not DSL).
And skip Sling. I subscribe to Amazon Prime, Netflix, and Hulu. That's it. I have a Roku 3, which I can get tons of free channels. I get my regular TV stations through an antennae. My bill is less than $20/month, not counting the Prime which is paid up front annually.
But, can you watch Fox Business, live (with this set up)?
