Antenna for OTA channels - I built this one:

HD Homerun connected to Windows Media Center on win7. I can watch through xbox360. This is only needed for DVR capabilities, it will work just fine if you connect your antenna directly to a TV
Roku3 for netflix, amazon prime, there are other services as well, such as Sling
I got Sling when they had their special, $50 off a Roku3 with 3 month commitment. It was a decent service, the picture quality was good, but it failed to deliver for live sports. The only chances I had to test it were the NBA playoffs, and in every game the feed was sporadic at times. It was not good enough yet to depend on it for college football
This fall, I signed up for cable again for college football. Sling was not good enough yet, nor are other avenues for streaming games online. I could also just go to a bar or restaurant to watch, but I would end up getting something to eat, and the cost would have been the same or more as just getting cable again for football season. I also like having NFL network for the fall. I'll cut if off again after bowl games, just like the last 2 years. All in all, $200 additional over 4-5 months for college football is worth it to me. NFL is OTA, so that isn't an issue. I still use the antenna for NFL because the picture quality through the antenna is better than through cable or satellite anyways.
