Any well designed vise would fail safe – the handle should bend before destroying the vise by over-tightening.
I would say get an old one, of good quality, and replace the jaws if necessary. There are loads out there at good prices (I know a man who buys most of the decent vises at a regular auction I attend, cleans them up, paints if necessary and sells them on at a good profit).
If you don't like it, or prefer another that you come across, just swap it out and sell it for about the same as it cost you. Shiny new vises are money pit (if you make the wrong choice).
