I think my Destiny set is the biggest, I have the 'Archive' versions that are unaltered for the toysite photos then I have the customs. A friend who I have not heard from in maybe a year from the UK made me the eyestalk for my dark grey squad commander.
The hard part has been finding the correct ear lights for the Chase thru Evil daleks. I would gladly swap the domes for those people who are not that picky for them as part of their collections. would have been nice if a second collector set dalek had those ears corrected like the Day Gold leader was.
