I know of about a dozen places that do carry BGC 
cels (most places nowadays prefer to carry BGC 
2040 cels instead of ones from the OVA), and a 
lot of them overcharge for them.  Cels from Crash 
have generally been cheaper than those from the 
OVA (I've gotten quite a number of my Crash cels 
for under 20 bucks, some as low as $5-$7), and 
from my experience cels of Sylvie and Vision have 
been particularly expensive.  I have three Sylvie 
cels ($65, $150, and $59, respectively), and I 
consider myself lucky just to have those.  I do 
NOT have any Vision cels yet because they 
routinely go for hundreds, espeeeecially ones of 
her from the ep. 7 opening *shudder* ($500 and up 
for the really good shots of her).  And it seems 
like hardsuit cels are getting harder to find...

And need I remind you that The List includes not 
only my cels, but all my other BGC-related 
goods?  You have been warned...;)  (I think right 
now it's at 6 pages on 10-size font...)
