It's time to upgrade from my 30 year old Jonsrud. I had a couple Stihl's before I got the Jonsrud and found it to be a great saw for all these years. I live in Alaska and cut softwoods, spruce and birch. I want a 16"bar and the lightest, most powerful saw I can get for $500 or less. I like the specs (8.8 lbs and 2.4hp) on the husky 339xp but maybe I'd be better off with the 435 or 440 for $200 less. I'm not to sure if the 435-440 is durable enough though? I'm looking for proud owners to chirp up on what they like and recommend.
