I am a fan of Evangelion, but I don't collect 
cels from the show(Geez, just collecting the 
series I do already breaks the bank for me.) I 
look around for cels of Rei and Misato, and 
usually people ask between $250-$1000 for a cel 
of Rei, depending on the shot. Most of the time, 
they tend to sell in the $700-$800 range. Good 
luck.
