If you're wired for cable, you can just put a single antenna in the attic/on the roof/where ever you can get reception and hook it into the feed going into the house. As far as buying fire sticks and all that, I figured I can buy a FireTV box per month for what I'm saving over DTV. I have four TVs and I was ahead in the 3rd month after switching to Vue (highest package they offer). If I were to have bought fire sticks, it would have paid for itself in like a month and a half.
I was a huge fan of DTV for a long time but after switching I don't miss it, at all.
