THX1138 is a standup dude, I know him from the Replica Props Forums, and suggested he drop a note over here about his cases, since there are a lot of Kubrick collectors.
I'm holding off on buying another case, because I think R2's bubble may be deeper than the other two. I want to get him and try him out in one of my cases first.
I did get my cases from Dan at KennerToys.com and they are top notch. I will probably order some Animated Series cases, and Saga cases for my special figures. Nice stuff all around.
