I am looking for a used large saw,(24-48") I will be using it for a firewood saw. Many of the trees I cut are standing dead oaks in pastures that get up to 36" diameter. I have a husky 246 for most of what I need to do so wieght isn't as important as power and price. I've been looking at 044's 046's, 066's 372's and 394's. Right now I am leaning towards an 066. Will all of these saws handle a 24-28" bar in dead oak? are there any I should stay away from? What are your likes and dislikes with these saws? Are there any good sources for used ones,(I've been watching e-bay); I don't think I'd use it enough to justify buying a new one. thanks
