I've never used Anime Chaos' deputy service, and 
Rinkya only once way back when. Though I still 
continue to use Celga, I have special ordered 
items through Akibado and find them very reliable 
and friendly (though a tad expensive).

They have started doing auctions, as well, if 
anyone cares to give them a try. Link here:

Good luck,
