Since the last half dozen guns I bought were off of Backpage ads and purchased at "My Office" which is the local McDonalds parking lot; I guess I have to say McDonalds is my favorite dealer. I purchased a mint condition Colt Trooper there while eating a Big Mac but you have to be careful about getting any sauce on the finish!
Most of the other guns I buy are from vendors at shows. Most of the major dealers(Cabelas excepted) including William Larkin Moore set up at our large gun show so there's no reason to go shop to shop.
As an aside:
I used to love going to Mandall's Shooting Supplies in downtown Scottsdale. Marty, the owner now deceased, was a real hoot. I bought a W.C. Scott SLE from Mandalls when they auctioned off the inventory.

I was too young to really know Marty, but he was, as you say, a hoot. Wish I could have attended that auction.
I'll give you an example. As the auction company(Greg Martin) was in the process of setting up Marty was running around behind them pulling guns out of the auction and putting them in his car.
I spent several thousand dollars at that auction and in retrospect I wish I would have spent more. The deals guys were getting were amazing.
For example: I bought 3 brand new rifle scopes that were without boxes and bundled together with rubber bands for $75. They had many of these bundles in the sale. When I got them home one was a Leupold with the $475 price tag still on it. The other two were nice scopes each in the $200 range.
The guy sitting next to me bought the finest Sauer double I've ever seen for a song and the auction company threw in a graded L C Smith with Damascus barrels!
