My local dealer has Taiwanese clone of this style
that sells for $190. It appears to be quite well made and works smoothly.

I bought the Taiwanese model from a Woodcraft dealer. It is a bit crude, but
quite well made. They told me Lie Nielsen bought a bunch for their use.

I also considered the Tucker, but at $700, I am pretty confident it is not 3
plus times better than the Taiwanese vise, which is an Emmert knockoff. It's
heavy, and seems to do everything the Tucker does, except it does not have the
smaller carving jaws on the bottom (I don't carve), and it does not ahve the
chain, which lets you open the vise with a foot pedal. I assume the fit and
finish is better with the Tucker as well, but for $700, well......
