i'm a stihl fan. your going to find that you need/want a bunch of different saws for different jobs.
clearing trail with a chain saw sucks. you'll need brush saw aswell as light saw to cut smaller trees. then you'll need a medium saw or 2-3 for falling trees/ firewood. then some large saws for milling(bridge building ect). chainsaw winches are also very handy.
eventually you'll have to many.
