I sometimes look at Marketplace or Craig's list, search for "Scroll Saw". I look to see what is offered for sale and ask myself "why are so many of those are for sale?" I see lots of the entry level saws, a good many DeWalts and a good many Hawks. I seldom see a Pegas, Seyco, King or, for that matter, any of the Taiwanese manufactured EX clones. And I almost never see a Hagner newer than 20 years old.
So I ask "Why?". The answer of course is supply vs demand: the one group has more sellers and the other has more wanting to buy them. People who have a Taiwanese EX clone or a newer Hegner are keeping them.
