Davison Lodge (dorm style lodging) is generally the cheapest place in town. It's well maintained but you are sharing a bunk room and the bathrooms. Davison also has a kitchen if you want to prepare your meals and a common room with TV.
Janaury midweek is somewhat slow. You should probably call around to the reservation services to see if you can get a 1BR 1970's vintage condo for a reasonable price.
