There are quite a few variations regarding their cleaning kits:
Fix-A-Game Cleaning Kit

and another controller, Canadian version:
Controller - Hot Turbo Action
I can send you pics through msn or else I can upload them to photobucket if you want. I think there may even be more, not sure if I ever went through all of the different Doc's cleaning kit pics that I have to compare for differences.
