How are these vices rated in the grand scheme of things when comparing like for like? I have one I forget about and found the other day under a bench. It is a brute and seems good quality. It has the quick release mechanism.
Parkinson are my preferred make of vice. Stout things, and Parkinson was the main innovator with regard to what we now class as the standard vice design. It also seems he may have been the creator of the QR mechanism.
