Firstly, that Jinnai cel on Taro is special. ^_-
I can place the scene directly out of the OAVs 
and it has a background. I personally would've 
gotten it... Popularity will play a role, but 
(from my sources), Taro doesn't always get cels 
straight from studios as you might think. That is, 
they may get cels from private collections, and 
you should know what that means.. ^_^''  Drac is 
right, too - they're still uploading from the 
previous crash.
