And I suppose there's a reason for that.  I have 
a tendancy to like less popular characters, so 
it's pretty common for me to see a group cel that 
includes one of them cost more than a cel of them 
by themselves.

ie: although this trend has been dying down a 
bit, it's always seemed like good group cels of 
Ruka from TNN always popped up with high prices 
because Gabe was in them (putting most of the 
cels I'd seen from the "dance" scenes above my 
budget)
