I like this line of thinking. Newer, faster, lighter, smoother, is all OK, but some members seem to be a bit too quick to dismiss older saws as obsolete and not worth messing with. Obviously for many of us, there is a hobby/collecting aspect with saws that goes beyond simply the need to own one as a tool. (And it's not like anyone around here just owns one saw either) I enjoy bringing along an older saw and giving it a workout now and then. Different feel, different sound, but you still end up with a pile of wood, right?.
Of course, anyone in a pro user category probably wouldn't want to be messing around with older saws, although there are some exceptions.
