To be honest, Knowing Tormach, I'm not sure the one I bought from Little machine shop years ago is any different than the ones posted on amazon right now. Most likely all came from the same place. If you do buy it, I'd suggest replacing the set screws right away. Made from soft cheesium....The rest of it is pretty decent. IMO the wedge type is much prefered over the plunger, and these repeat very well. I made a bunch of extra holders for mine, and was planning on making some more, but will most likely buy some now that I know they're that cheap.
