I remember a few years ago when people really 
didn't care at all about any cels from Sailor 
Stars.  You used to be able to get cels of 
eternal sailor moon SUPER cheap because noone 
wanted them!!! Oh how times have changed!! Now 
cels from the sailor stars series tend to go for 
more money than the other series.  There is good 
reason though,  I find sailor stars cels were 
animated a lot better than the other sailor moon 
cels.  Not that there are not plenty of gems from 
the other seasons but I do really like the art in 
sailor stars.
