Don't own my own, but my parents heat with nothing but wood all winter, dad swears by his Husqvarnas. (sp?) Think he finally got a new one after 20+ years of running his last one... And iirc, they go through 16-20 double rick of wood a year. He does have a McCullogh (sp? also) with longer bar for big jobs, but the Husky is his go-to. 20" bar I believe.
