As a bit of a puzzle collector myself, when I stubled upon this unusual Rubik's I purchased one right away. Only available in one small city in central Japan (as far as I know) these cubes feature traditional Sarubobo good luck dolls. I'm selling a limited number through my eBay store for $18.99 each. If anybody is interested check out http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=220019716334
to see pictures and for more information about Sarubobo.
