I took the plunge and switched from AT200 to Dish HD with locals. It was a breeze. I also made sure that they added the free public interest channels. The CSR had to check with his manager but it didn't take very long. Calling at 5 p.m. usually gets me an American who can actually help me quickly and does things correctly. I'll miss my RSNs but I'm saving a bunch of $$$. They really need to let us add the sport pack. I wanted to pay for it but they wouldn't let me. I got to keep these channels for some reason:
AMC
IFC
Fuse
Hallmark
Those are free preview channels. Those should change periodaclly.
