Your best market for maximizing your sale price will be to sell it to someone walking the floor. The dealers are there to make a living, or at least turn a profit, so they've got to buy at prices that allow them to make a buck. John Q. Public walking the floors might not be as concerned about his margin, but just remember, lots of dealers walk the floor from in front of the tables too.
I know, I am both as well
Have two tables at the upcoming Spokane show.
Sometimes I take a gun off of my table, remove my dealers name tag and the guns pricing label and 'walk it around some' to see if I can garner more interest in that particualr firearm and to see if my pricing is about right or not.
