I began DirecTV Now, 3 weeks ago. There was a AppleTV 4K promotion (which still may exists), where you pre purchase 4 months, and get a free 23 GB Apple TV 4k. It took e 2 weeks to get it, and it is working very well. I have a 25Mb AT&T Dsl internet connection, and it has been solid. Compared to my ROku 4, and Fire TV, the Apple TV works the best with DTV Now.
I have the $55 "Just Right package." Because I also have AT&T Unlimited wireless phone service, it is only $40, instead of $55. Check to see which locals are available in your area, if that matters to you. In Gulfport, we only have Fox available to us. So, I'm slave to the antenna for the rest.
For the Record, YouTube TV is not available where I live (due to no carrier agreement with local stations). As soon as it becomes available, I'm moving to that service.
