I scored one of the old StarChoice dishes, I stopped in at one of the Rat Shacks (The Source now) that did install and he had a couple lying around behind the back of the store, he just said help yourself, please.
I guess they still do a few new installs for Bell with the small dish and when asked have to remove the big old dish, its a nuisance to them, another trip to the dump they have to pay for, so they are usually happy to get rid of them, you might try a few dealers the price is right.
A 1 meter dish is the minimum I would recommend around here, with my line of sight I get everything from 87 to 129W at a reliable signal strength, although I will lose PBS on AMC3 in really heavy rain.
To give you some idea of signal strength (signal strength meters vary to much to be a good guide) I could just get a signal in perfect weather from PBS on AMC3 with a 33" dish, the 1 meter plus ex StarChoice dish has good signal strength except in really heavy rain on the same channel.
It seem that as you go further east you start to head out of the footprints of a lot of the satellites that are aimed at the center of the continent you can still get them, you just need a bigger dish than someone in Ontario even if you happen to be further south.
