Time ago I contacted with the webmaster of this page:

http://www.geocities.co.jp/Playtown-Toys/9329/old/topic.html

where you can see SD Snatcher on sale.
I finally didn't buy it because it came without the manual.
I remember that the seller sent to me some pictures of the package. Price was (is?) 11000 yens.

Maybe someone is interested (if it is still on sale).
