I don't know about this. You look at used firearms on GunBroker and everyone sure likes their stuff. $$$
Gunbroker is an example of nothing. It's just a bunch of sellers fishing for suckers
I would largely agree, with the exception of no reserve auctions. I think that completed no (or low) reserve auctions are one of the best current measures of what things are actually selling for.
The remainder of sky high listings are pipe dreams looking for smokers...
