I posted the story about how I came across this zapper in my Finder's Keepers thread.  I am curious about the price that this zapper could fetch.  The inside contents appear unused, new, and pristine.  Even has the CoA in there.  Foam is also in great condition.  The outer box, not so much.

I just sold mine in an auction for $26 CAN, mine had tape damage on the back though

Mmmm gray Zappa. I'd say 40 they are more rare than the orange ones.
