Best dealer on Ebay to purchase authentic new Oyaide products from

I'm wanting to purchase a set of the Oyaide Focus xlr plugs and don't want to pay the $100 + mark-up from US sellers.  I was going to purchase from Smart Imports of Japan but their site has been down for a couple weeks now and no way to tell if it's temporary or not.   Who are reliably authentic Oyaide sellers on Ebay?  Any other seller recommendations?  Thanks
