I think the big question here is what terrain/conditions are you looking for? I think I've seen a lot of excellent suggestions for affordable ski towns pitched, but if the skiing isn't a match, the affordability part doesn't register.
Jackson Hole was thrown out- is that the type of mountain you are looking for? For the steeps, the snow, or both?
Is a small/less crowded place considered a plus, even if you are giving up stuff like vertical drop and fast chairs?
