Hey, I think what you're doing is really cool.  
Ya never know when an extra cel is added to your 
shipment is actually meant to be a gift and not 
a mistake from the dealer or whomever.  I'm 
still missing 3 cels from a previous transaction 
with somebody...but pretty much gave up on all 
of them, even though 2 of the cels were from a 
pivital scene from on my my absolute favorite 
anime titles...  Really a shame, actually.  =P
