Well, there is the person who had posted recently 
on the forum - don't know anything about him/her 
personally, haven't used them (I use Sato - he 
will negotiate the transactions even when you 
bid), but here is the URL:

Also, one thing to keep in mind is the extremely 
high shipping fees to get your auctions. In 
particular for books.  I ended up paying 130.00 
in shipping fees for a 60.00 auction because of 
the weight.  Overall it was worth it though, 
because purchased individually the price would 
have been insane. But, it is something to think 
about on heavier items - like the DBZ hard 
covered art books. I've restrained from buying 
those because of shipping costs. I've seen them 
go for 40-50 on ebay, but there are a couple of 
online shops that you can purchase them for 
around 25.00.
