I agree, Al. I had a 40cc saw (Jonsered 2141). I ended up moving up to a 50cc 2152. About the same weight, but 20% more HP. A nice little saw, but still enough "oomph" that I can use it for firewood cutting when I've already got it in my hands (at least on the smaller logs).
For what Just Me mentioned as his primary purpose, the lighter weight, and cost, but still more power than his old saw should work out well for him. I don't imagine he needs a whole lot of power to cut those slots in the log wall, and if it's a long cut (sometimes at awkward angles?) the 1 pound lighter weight than his old 240 ought to serve him well.
