My bad, in an earlier post I said it was about the weight of the 150, but I meant the 201. I was going to make a comment about the engine displacement being between the two, and must have lost my train of thought. With both of them fueled up and full of bar oil, I didn't notice any difference in the weight. I did notice the difference in the balance and size of the saw, however. I think the 200 and 201 have the best feel and balance of them all, so I honestly don't expect any other saw to be as good in that regard. I like the Tanaka because it has enough power to do the job, has a pretty nice overall feel to it, and costs about a third what the Stilh 201 costs. Cheap enough that I don't mind letting other people use them. I don't let anyone touch the Stihl saws, because if I break them I have only myself to blame. If someone else broke them, I'd feel bad while I was disposing of the bodies, so I just don't let anyone use them.
ML, I also really like the look and weight of the little 150 and think I'd like it. The small engine doesn't really bother me... when the work requires more power, I'd just switch saws. I think it would be nice to have a very light saw and get all the little stuff done first, rather than lug a heavier saw around the whole time. But I do lots of things differently than most folks, and I have a lot of patience on a jobsite.
Another saw I had considered was the 192T which is lighter than the 201T and I think the engine is about the same size as the Tanaka, if I remember correctly. I see a lot of them in use, and we call them the poor man's 201, around here. I've never heard any of the local guys complain about them being too gimp. I only see that stuff online. One guy, who isn't a climber but manages an outdoor power shop (he does own a bucket truck), cuts more firewood than anyone I know and says the 192 is the saw he uses 80% of the time.
