Comcast Data Caps …. Live TV Options

So I have a family of 5 and the streaming from Netflix, Amazon, PS Vue, and all other sources have been causing me to use approximately 1.5 to 2TB per month.

The only way to stop this is to eliminate some kids and make it a family of 3 but I couldn’t decide which ones to keep. The next option has been to either add a Tivo or an HDHomerun (not the crappy comcast box).

Cost wise I think the HDHomerun is the best choice but I was wondering what is the best live tv (easiest to use for kids) to use with Kodi. I was looking at the Silicon Dust solution or possibly a mythTV option. I went to the LiveTV forums and there are so many options. Figured I would at least ask for a good place to start.
