I think buying a used vise is like buying a used gun. For me, if I go looking for it, I'm in trouble. If I luck into a great vise at a great price tomorrow, I'd probably grab it. My thought, never let the seller know I'm interested, you'd think the 'patina' was a quarter inch of gold.

Last vise I picked up I noticed in a scrap pile when I was picking up a few pieces of steel for something else. I asked the fellow at the yard what he wanted for that old thing, he said he'd take twenty bucks. Not bad for a browned but not rusted or abused Athol. It's a great vise. Recently, I was really interested in a 22lr rifle. It became one of those things that the seller started thinking it was worth its weight in gold. I'll never inquire about that rifle again, there're so many other interesting things out there.
