Hi Alan, remember you only get what you pay for, have bought two different models - cheap as chips but for the cost of postage, which would outweigh their value you could have them from me f.o.c.
jaws are alloy, don't line up very well, not a smooth operation and if only using one side of the vice, especially for holding small parts, the jaws tend to 'yaw' i.e. lock up on a taper.
At the end of the day it's down to budget and intended usage, they all work - as always some better than others.
Good luck with your search and kind regards, Tony.
