It's actually not terribly expensive... not that it's cheap. But I've got friends with slightly above average income that spend at least as much as me on golf, or guns, video gaming (compys are expensive) or well a lot of stuff. Hell a membership to a country club (yes I know you don't have to join one, just saying) will cost you more than my whole collection, and shiz I got a pretty good collection! Hell a buddy of mine has a single watch that's worth more than my whole collection. Hobbies in general tend to be expensive!
