3 is the most I have of anything, HK P7 PSP's. Its my favorite handgun, they don't make them anymore, and I scored them for half of their going rate. So really I justified it as an investment, and I could sell them in less than an hour at the rate I paid for them. I could get twice as much if I had a few weeks or months to find a buyer. I do have some doubles of spydercos that I like. Then I have some things that are almost exactly the same, Yard Hook/Guard, battlerat/dogfather and several things in my hiking gear. They're all things you can easily get your value back out of if you decide you want to get rid of them. Not so much the hiking gear, but I consider my second set worth of gear something I've always wanted. Gear for 2 so I can take people that don't have their own.

I did grab 6 of an awesome Mountain Hardwear shirt one time, the ZeO2 fabric, at about 70% off and kept 2, gave 2 to my dad, and 2 to my brother.
