Well,

First off Zetsuai is out of the picture^^;!  Only 
seen 2 in my entire collecting years...1 is in a 
gallery...& the other was recently on YJ...Which 
I kick myself for not getting it for $12!!!!! 
Grrrrr....
Next.....Ai no Kusabi.  I love it too.  I myself 
have 1 cel from it. One of Riki.  Sigra has by 
far the most though.  There are a good number of 
Ai no Kusabi cels out there...Mainly on 
YJ....BUT...There's a problem.  Recently...a TON 
of people have been out searching for them.  In 
the beginning, yaoi cels weren't hardly sought 
after.  Pretty much all yaoi cels went for what 
now seems INCREDIBLE prices.  You could get an A 
Grade AnK cel for UNDER 
$100....NOW...SADLY...You're seeing B Grade go 
for over a couple hundred dollars...& A Grade 
cels go for over $500...In some cases...Close to 
$1000.....-_____________-....These new prices we 
can thank to the people bidding OUTRAGEOUS prices 
for them on Yahoo! Japan.  So...Sorry to be the 
bearer of bad news, but unless you get EXTREMELY 
lucky, or have a ton of cash to bid senseless 
prices on...Your chances of getting on AnK cel 
are slim.  I hate to be posting this, but it's 
TRUE.  I've sat & watched all AnK auctions, & let 
me tell you...If anyone wants to say 
otherwise...Go right ahead -_-...Anyway...
I was lucky enough to know someone so kind to 
help me get one of the most BEAUTIFUL cels of 
Riki from AnK.  Which i got before the prices 
skyrocketed.  Feel free to browse my gallery if 
you wish.  I have several Yaoi Goodness cels ;)!  
Even some EXTREMELY RARE cels from FAKE.
