Grizzly has a version of the old Versa-Vise at a pretty good price, as well as bench vises and other special purpose vises.I think it is convienent to have more than one vise.I have two bench vises and a versavise set up as well as a small swivel base toolmaker style vise mounted on a 2x4, which I clamp in one of the other vises.This doesn't include my homemade barrel vise. You can't work w/o a good vise.
