First of all excellent site. I have an 045AV in excellent condition, but it weighs a ton. In the future I'm going to be cutting firewood to supplement oil heat in my home. I hope to provide more of the heat through wood as opposed to oil. I also have 10 acres at home that I need to clean up. My question is do I purchase the MS 260 for the cleanup and most of the firewood, and use the 045 for the really large stuff. Or, do I purchase the MS280 and use it for most everything, and anticipate purchasing an inexpensive frog hair saw in the future?
