If your house is going to be heated by wood stove and you live in the toolies where the weather gets rough I'd get the best I could get. I'd go for either a Husky 357XP or 575XP (I like the later). But so much depends on your budget, your house's insulation properties, wood availability and storage situation, help in felling, splitting, etc.
Here is some info about the 575XP from the Husky website.
