I wouldn't have an estimate on the cel because I 
focus on BD. However, the previous poster doesn't 
seem out of line.  

To give you a reference point for non-op cels, 
the ratio between a good cel of BD vs Keichi is 
somewhere around 10:1 to 20:1. AMG has one of the 
widest pricing differences between principal 
characters I've seen, male or not. 

I actually feel sorry for Keichi sometimes... 

Hope this helps,
Chi
