It sounds like a great idea ^_^!

However, I know that some of us might not want 
our gallery featured in a documentary just 
because it sometimes attracts negative attention 
(I know a lot of the "heavy hitter" cel 
collectors get stacks of hate mail from people 
who want to use their images for various things, 
etc.)

So, please just make sure before you use one of 
these "best" cel galleries that you make sure 
it's OK with the owner of the gallery :)

just my 2 cents,
