Look at it this way. If you need a saw smaller than the 441, the 362 isn't that much smaller. The 261 is quite a bit smaller and less powerful. I think a 20" bar would be a stretch for it. (I run a 16" on mine and a 20" on my 362) The 261 will fill the gap between your 180 and 441, but if you have big enough wood to really need the 20", I'd go with the 362. I've been happy with my Wife's 241, but I wouldn't trade it for my 261, which she uses a good amount, too. The saw I have that I wish I had purchased before I got the 261 is my 271. It's one of my all time favorite saws. It's not M-tronic, so was considerably less expensive than the 261, but I think it outperforms the 261. YMMV.
