I got my Klippermate around 1990. I got the Gamma dropweight with the ratchet in maybe 2004 or so. I got a Stringway ML90 a few years ago.
I should have bought the ratchet dropweight from the beginning, and I should have gotten the Stringway before either the Klippermate or the Gamma. Each machine improvement does result in some speed increase (not tons) - but that's no the point. The point is how much less annoying the whole process is.
Nobody paid for the opinions I express.
