I'm looking seriously at the 250. It seems to have a good weight to it and is heavy duty enough for what I do. I don't heat only with wood. I only cut a couple of cords a year.
I would spring for the farm boss but it is heavier. I'm not sure the trade off is good enough for me. With my arthritis I don't want to have a heavy saw wear me out. I am concerned about all of the things I read about them flooding easy and being hard to start.
