Haha, you got that right; there isn't much that gets to me; especially in the toy world.
Here is a little database I have been working on for a while. While it is far from being complete for all of the 450 series, I thought it would be worthwhile for a lot of people for reference to see what has been released so far. I think there are still some variants and newer versions I need to add, and all of the pics have been borrowed from various sources, so I will try and improve on it when I can. Any feedback is welcome of course.
