Hang on to your shorts and pony up the money for a Wilton. It's the only vice I have not been able to break.............so far. With my work I can get pretty abusive with one. I was breaking a vice about once a year till I spent some real money for quality. This is the current one I am using and have had it for 4 years now and did not even use all the holes to bolt it down.
