Here's one of mine that drove me to start this topic. One day as a kid, my brother and I each got a Transformer. He got Tentakill from the Seacons group, and I got Rippersnapper from the Terrorcons group. I didn't like Rippersnapper's stubby arms, and my brother had some problem with Tentakill so we traded. It's hard to look back and say how long it took but it was probably the better part of a year before we had both completed our sets. I played with Piranacon an insane amount. It was the only combiner I'd ever had and to me that was the coolest thing. Fast forward a couple of years, and my family was having a garage sale. For a reason I still can't figure out, I put all six Seacons, with all their weapons included, into a box and sold it for ten bucks. I don't remember what I did with the ten dollars but I know I couldn't have gotten enough out of it to warrant selling Piranacon. I kick myself to this day for that.
