Which one? I know the problems with the Dish and rain and storms and such. But what else? What are your preferences? As far as cost goes:

Comcast: Basic cable - $45/month for 70 channels
Dish: Basic package - $36/month for 60 channels(I don't even watch the 10 less channels, and I would watch a few of the channels the Dish has that Comcast doesn't)

Later, QD.
