The House of the Dead Gunset - Saturn - HK (?)

Can anyone provide a reasoned reference price for the very rare House of the Dead boxset for Sega Saturn?

This set, while including the Japanese version of the game, never came out in Japan but only in Hong Kong or China - I am not sure. Can anyone shed some light on the origin of the box?



Just for the record: I do own this box, but I do not intend to sell it. The price I paid is not really relevant because it was part of a bigger bundle on Yahoo Japan and nobody noticed it. I think I shelled out maybe $50 for the bundle which included another 20 cheap games.

Since this box is really, really hard to find (similar to Illbleed Limited Edition JPN), I would be interested in the origin and price on trading platforms. I never saw this sell in an ebay auction on its own.
