It's a Japanese shop called Mandarake (link below):
I bought the carded Anakin from there last year and was very happy. I bought the Maul for JPY 8,000 and as I recall there was another there for JPY 10,000.
Best of luck!
I got my holo Maul in the mail from Mandarake. Very happy with it & a hell of a lot cheaper than eBay. Me thinks the new site is going to be used many times!
Thanks Jonny for the heads up!
