Per the OP's title...Who Makes A Vise Between China & Kurt?..... Glacern is the only one I know of oft hand. The castings come from offshore but they are machined and assembled in southern Ca.
That might have been true in the past, but they have had an upheaval in personnel, and the business doesn't seem to be run the same as it used to. Several recent threads on various machinists sites have called this into question. YMMV, past performance, etc etc.
Conquest makes an awesome 5" vise (mini-magnum), which is the one that Tormach relabels. But it isn't any cheaper than a Kurt, and might be too large for your table (since you were shopping for a 3").
Wait for a Kurt to be on sale in Enco Sales catalog, and then wait until you can stack a 20% off coupon on it, and you get a US price for the price of an offshore one.
EDIT: since you are looking for a small vise, this might not work. I don't believe I have seen them ever have the Kurt 4" on sale, although you can always use the semi-monthly 20% sale to buy one. With a 20% off coupon, you could get the US Made Kurt 4" for near the same price as the Glacern 4" (Taiwan or China made, nobody really knows).
BTW, the Conquest mini-mag 5" vise actually has the same footprint as the Kurt 4".
