I look at buying guns at auction via the net as gambling with odds one whole hell of a lot better than Vegas if you are an educated bidder. I have been burnt sure but I have made many fold what I have lost playing the auction game.
I am not speaking to a dealers livelihood. Nor am I speaking as a gunsmith who can decide what repairs to make on his own dime. I am speaking as a guy who buys a gun to use for himself, with maintenance and repairs coming out of his pocket, and to let his heirs worry about the disposal of. That, is different by several orders of magnitude.
I will agree, setting foot in a casino, with the understanding that the entire game is rigged to favor the house, and, gambling anyway, is the very definition of insanity, and is something I have never done, and never will do. A side note is that you can expect the same long odds when dealing with some gun dealers.
Best,
Ted
