I've got a brand new Cox .010, which unfortunately the cardboard box it came in was destroyed in an ugly fuel spill incident (It was in a storage tote with a gallon of fuel that leaked). I've also got a brand new Cox .15 that was lucky enough to be above the fuel level in the tote. I'm just blown away that this tiny lil engine that I paid $50 for years ago at my LHS is now worth hundreds of dollars. I doubt that my OS wankel (the good "PI" one) would bring in that kind of coin.....
