I have heard bad things about the Miche hubs and thier winter durability. The same can be said of the entry level suzue, which I had to repack after 2 months of winter riding here in Minnesota (which is quite snowy/salty/wet). Follow taco's advice with the sealed hubs, I would recommend suzue, or suzue promax for winter riding. Both forementioned hubs are not extremely expensive and have sealed bearings. Just don't sink oodles of moolah into the wheels, because no hub will survive forever in such winter conditions.
