The problem is, that Boba was one of the first to have arms on it. The ones previously were true busts; no arms. Not to mention that Boba's a hugely popular character, it only made it worse. Compound on that the fact it was a more limited run, if I remember right, and very few are letting him go. Personally, if I were after him seriously, I'd set aside an amount that I know I could get him for and call it a day. If that were the only thing I was after at a con, I'd be prepared to pay premium for it and be done with it. Take for example my Biker Scout mini bust that I finally got at CV for $55. I was prepared to pay as much as $125 for it that weekend, and was lucky as Hell to find it for what I did. It's all about what you're willing to pay for it and how bad you want it, and finding that middle ground.
