One suggestion- both Auctionarms and Gunbroker have a "Find a FFL" section. These are 01 and 02 FFLs that have registered as being willing to receive firearms and do the transfer to the recipient- usually an auction winner.
Some dealers charge $100 per transfer, which, IMHO, is outrageous. $20 is reasonable- or free to a good customer- or free with purchase of ammo, etc.
Time waster? The guy that wants your time to educate him on a model 21 vs model 23 etc etc etc, then buys it at bigstore with live fish and airplanes in ceiling because it was $10 less, but wants YOU to tell him why it is not working right.
Waster #2- the guy that wants to sell you his 11mm Grunchenticker for $XXX.00. Because the "book" says it is worth $XXX.00. Yes, if it were THAT model (it's not) in New In Box shape (it's not) that would be the RETAIL price of one.
