I have the tivo OTA box. It's great! I ended up having to spend another couple hundred bucks on a rooftop antenna though. I also got the tivo mini box for the living room (main box in the bedroom) to share the DVRed stuff. They even have common apps on the box too like netflix, hulu, etc. I rarely if ever have to switch off of the tivo.Anyone use this?

It would be amazing if Tivo + Sling somehow worked together and you could record Sling broadcasts for DV-R-like consumption
Just realize, you're paying $15 a month for the tivo service though.
