I've had DirectTV for about five years or so. They have been great. When we had a box go out they overtightened me a new one with no questions asked. I have the protection plan and it is definitely worth it.
The technicians have always been clean and professional.
I moved and had to take DirectTV with me. Would not trade it for any of the other options out there.
Only complaint is that they don't carry TheBlazeTv. Hopefully they stop giving in to the politics soon and decide to add this to their channels.
Overall I have been extremely pleased with DirectTV and would recommend it.
