Mike I guess by real world weight you mean with bar and chain? I agree it is difficult to compare without including and I know the Makita weight I have is power head only, the 038 weight I found may include a bar.
Anyway, yep they are heavy. I use the 180 for 90% of my saw work. The big saw comes out for noodling unsplitables and bucking the occasional larger round that I've collected that is still too long for my small stoves (12" or less is the aim). I tend to make a pile of half a dozen pallets as a temporary work table, lift rounds to that and cut. Very occasionally a big round is easier to cut down on the ground. I'm not bucking or limbing out in the field like you guys. So weight is less important. If I were starting again, knowing now what wood I get.... I'd likely have just one saw and it would be a 241 or 261 sized machine for everything.
