Website with large collection of reasonably priced stones.

Was wondering if any one has ever checked out http://shoei-do.net/. It has a huge selection of stones including
naniwa- chosera, diamond, and super at crazy prices.
shapton- pro, glass, m5, and m15
sigma power
imanishi- bester, arashiyama, kitayama, and another 8,000 I have never heard of called otokoyama
king- including diamond which I have never heard of
Also some really expensive suehiro's at 15,000 and 20,000

Has any one ever heard of them. The prices seem too good. They also have some knives but I wasn't that impressed.

same dude on ebay that sells them. that's just his private site. =D
