statues/busts are the more 'mature' way for a non-teenager to hold a collection and not get made fun of for it... but damn, you'll pay for it. I have all the SFIV figs they've released so far - including Ryu, Ken, C. Viper, Chun Li, Guile, and Akuma.
Those figures were around $16 each... find a Ryu statue and you're talking easily over $100.
