When I first started collecting, I would 
basically go out and get every cel I could from 
that series. Some of them were downright awful 
cels that I paid too much for. I little later on, 
I began to realize that my gallery needed to be 
more about quality than quantity. I think within 
a span of a month, I dumped half of my 
collection. Now, I focus on only a few series: 
Outlaw Star, Gundam 08th MS Team, Tenchi(Ryoko 
cels) and Trigun. I might buy a DBZ cel, but I 
have only three scenes that I would care to buy. 
I don't think I've purchased an Outlaw Star cel 
in several months because most of them are either 
way overpriced, or very generic. I would consider 
collecting other series, buy only one or two 
scenes for each one. I'd like to get cels from X, 
Elementalors, CCS and Slayers.
