I totally understand trading and selling that many. I've been through more than 20 this year and only have three at the moment.^^^ why would you trade/sell that many?
I've only bought 3, the Para2 in camo, Manix 2 in DLC, and the one that started it all, the Tenacious. Many more to come, can't wait.
None. Zero.
I already own more Spydercos than I can use. They are my favorite knives. But I decided to find and buy models of other brands that appeal to me this year. So far, the pickins are slim compared to the number of interesting Spydercos yet there are a few out there and I'm pursuing those right now. Before 2015 ends, I'm sure I'll succumb to another Spyderco (or two).
