I guess I would consider myself an active Sailor 
Moon collector.  But for budgetary reasons I 
usually get only about one cel per month, and 
started a little over a year ago, so that should 
give you a good estimate of the size of my 
collection.

For anybody that cares, my focus is on Ami/Sailor 
Mercury.  I do have a few cels on the way, so 
maybe I will do an update within a couple weeks.
