I am with Rope on this. Get a 70cc saw and you are set, I own em' all and this is the "go to" class (372, 440) That should be everyone's first saw. As far as people whining about cost and weight, not a factor in the big picture. You will condition to whatever saw you run, resale value will be there if you buy a pro saw and treat it right. Now, with different length bars you are set, I would get a 20" to start, then expand the collection as you develop. Don't bow to the minimalist mentality, do it right, right away. If you want another saw latter, you can go up or down from there. BTW, 70cc is not a "big" saw, it's the standard for woodsmen around here.
