Dear Starfighter,
   Hello and welcome.  Yes I only specialize in 
this anime.  My site Serenity's Cosmos is down 
right now until Sept 1st, then I will reopen. I 
am waiting for a few new cels, my internet 
provider went bankrupt, so it's taken a while to 
sort out, but it's almost complete, including an 
extended links page with over 30 SM galleries, 
with descriptions of each site & their special 
cels.
Rare cels.... well Saturn, Pluto, Angel Usagi, 
Starlights together, Mistress Nine, Chibi Chibi, 
Neoqueen Serenity & Queen Serenity.  
Rare episodes....(or popular) episode 200 Angel 
Usagi fighting Chaos, Endymion together with 
Angel Usagi, Nephlite dying scene with Naru, and 
my favourite ep 194 Seiya and Usagi on the school 
roof (pic attached).  
And yes there are many VERY NICE people ^_^who 
collect SM cels, not to mention other anime, this 
forum has many helpful and wonderful people who 
will gladly share their knowledge with anyone, 
all you have to do is ask.
  Jennifer (Serenity's Cosmos)
