You said it. No single provider has it "all." Each will have advantages and disadvantages, and "true" local on the 8's provided by local cable operations is one of them, among others. There are some Dish subscribers (usually on the west coast), about as many as those who request "true" local on the 8's (meaning close to less than 1% of all Dish subs, IMHO) who consider satellite's use of only the east coast feed (with a few exceptions) of channels to be source of complaint, and they prefer the pacific feed instead. Well, that's another reason to keep cable or other service that provides the feed for your region of the country, if that is what one wants because satellite just doesn't have the capacity to provide all regional feeds--in HD, no less-- any time close to soon with the current DBS infrastructure.
Please, let's put this in the pile with "When is Dish gonna provide it's own broadband internet solution with speeds like DSL or cable?" and "When will Dish provide VOD the way my cable company did?" or "When will Dish play my community's local commercials advertising restaurants in my neighborhood like my cable company did?" etc.
Those things are not easy to provide with the current DBS infrastructure that was designed over 15 yeas ago while today satellite has considerably more pressure form customers and competition for more HD channel capacity, especially ALL LIL's in HD, and especially all PBS locals in HD ASAP pressure coming from Congress (and subscribers) applied to Dish.
If such features as the 8's, etc., are really that important, then would seem to be better off to wait for DBS to solve these problems. Yes, perhaps, doable, quite a bit in the future, but not soon enough for a demanding individual customer to make him happy. In such a case cable would be the ideal service provider for that person.
