As a kid I was never really into Lego's. I was more of a science kid. I had chemistry kits and microscopes. I was into Mecano, the steel version of Lego's I guess you could say. Also I was into plastic model building, like cars, planes and boats.
After seeing this video http://www.wimp.com/workingguns/ I think I want to get into Lego's. Now if they had Lego's like this when I was a kid I would of been into them Big Time! LOL
If I could find some of these sets I would purchase them just for collection purposes.
