I'm colleting those, but as you mentioned - they're damn expensive.. I buy like one in a year, and then I bloody hate myself for spending so much money. T.T But lately I found such a good solution - PAPER CRAFT! Just.. Google it. It takes a lot of googling, and some might be on deviantART, but it's absolutely worth it.. Also it's a great solution if you have too much free time on your hands and have no ideas how to spend it...

Myself I own Fate/Stay Night, Bleach and Sonic figurines.. I usually spend money for other stuff, as over here, in Lithuania, we don't really have any good anime shops storing figurines, and ebay or amazon.. They're just too expensive.. -sighs-
