Hi, does anyone know how much these calipers are worth these days?? Have got a set sitting in my garage and thinking about selling, and would like to know how much can I ask for them??

Normally, I just search on EBay at what price they sell it and put it along those lines.

Of curse I did that, but sometimes just because somebody advertised it in some price it dose not mean that is worth that... currently there is a set for 585 pounds so if they really going for that much -
