Re Sattelite dish:
My purchase was March 2011. The coach came with a KVH R5, in-motion dish. This can see only Dish, Direct and Bell. Neither of those are suitable for Canada and US. So if we can get rid of that bit of roof top ballast, we will.
Shaw, on the other hand, has just given us a dish for our summer home on Saltspring Island, and will provide a sattelite dish for our coach, or for our boat, or both, and even for our home in Coquitlam, when we get around to it. All on one monthly rate, cancellable for any period of two weeks or more, up to 6 months. For the MH or the boat, the $99 dish they will provide, on a $50 tripod, may not be pretty, and of course won't work "in motion", but since most of our TV watching is for the 11pm news, the fancier ones seem a bit extravagant. Both Wineguard and Motosat have "in motion" dishes that can see Shaw, but, as Jeff notes, at a high cost.
Shaw also claims their coverage is the broadest of all, stretching up the BC coast as far as Alaska (relevant to boating) and down to Mexico, should we ever stray that far south. The only downside I can see is giving up a little stowage space while on the road.
