They were significantly better made than today's offshore stuff, however whether it is still better depends on condition. In other words it might of started off better, but is it still? I'm doubting it. Brent has spotted some interesting stuff. It really does come down to condition/wear as to whether that is really overpriced or a great deal. Brent is also in Ontario where the livin's easy, and the lathes are cheap
20 years btw is nothing for lathe, if was well cared for and constantly lubricated.
As for parts, what parts? I've reconditioned several lathes, have a dozen and fixed and sold more.....never once have parts been an issue (unless one busts castings, but who does that?). There is just very little that isn't fairly easy to make or a commercial item. Its easy to be wrong making generalizations, but that has been my experience.
Me, I'd keeping looking. They are a great lathe, but I'd rather pay more for one in amazing shape with lots of tooling or a small fraction of that and recondition it (remove the wear). But you're they guy ground who can assess condition and wear.
