In the specific instance I'm considering, I know the original price of the gun and the current conditions, so I think I could figure it out, but I don't have the charts.

In my case, I am mostly just curious. I'll buy the gun (or not) based on what it is worth to me, which may be far above or below market value, but I don't really know what market value is, and I'm curious.

Rocketman, if you share those charts with others, I would greatly appreciate a copy of them.
