Shotguns, specifically trap shotguns.
As Forum Member Perazzi noted a Perazzi Combo Trap gun is expensive (that's a single barrel, either top or unsingle and a set of matching over and under barrels).
New, they run about 10-15 thousand. Some a little less, many a lot more.
I have one. And, several other trap guns, one of which is a used Perazzi with one top single barrel my wife shoots that I got an absolute steal on for $1700. I also got her a used Beretta Combo for another $1700.
My Perazzi combo then needed release triggers and I bought two, one for the single barrel and one for the over and under. They cost, new, $1100 and $1400 each and have the original life-time warranty.
And, all of them needed stocks, so I bought Precision Fit Stocks, which, new, are about $1200 each (I have five of them).
But, I cheated on the cost of the combo, the triggers and the stocks.
Fortunately for me, when I first started shooting trap, an All-American trapshooter (that's a big deal in trapshooting) and her dad, who had been my K9 officer when I was a young police sergeant, took me under their wings and explained the facts of life concerning trapshooting to me.
It seems that many trapshooters change guns about as often as some folks change their undergarments-about every month or so.
Or, and this defies explanation, many shooters shoot a great score, like their first 100 straight, and then they sell that gun and buy a more expensive one (as if the new gun could help them shoot a score higher than the perfect score of 100!).
So, I bought the combo that had belonged to a guy who had just won the Handicap in a State Shoot beating all the other several hundred shooters there for 5K. The triggers were purchased used from a Precision dealer who got them from shooters who wanted newer ones for about $1900 for both, and all the stocks were purchased from shooters who liked the adjustments and lack of felt recoil of the Precision Fit Stocks, but liked the look of wood better for about $750 each (Precision Fit Stocks look like an artificial arm or prothesis).
My least expensive trap gun is a BT-99 by Browning, which I bought slightly used, added a Precision stock and a release trigger for about $1400 total. This one just stays in the safe or the back floorboard of my SUV as a back-up in the unlikely event my Perazzi goes down in a big shoot somewhere.
I have been tempted to buy new guns after shooting a good score, too, but, so far, I have managed to avoid the temptation and "make do" with the used Perazzi.
But, I am always on the look-out for the guy who wants to sell his gun cheaply to buy a more expensive one. Many trapshooters think they can buy more broken targets by buying more expensive guns. (I told you this defies explanation

).
And, I like to be in the vicinity when they decide to make the change-glad to help them out.
