Link's up top.  Looks like a fan cel, too, but 
the other SM they have probably is real.  Perhaps 
they both are real...the coloring on the Rei 
looks odd, that's all... *shrugs*

But, I have seen these on Y!J.  They are 
currently auctioning up there, for much cheaper 
prices.  So it does sound fishy, if nothing else.

1111  <-- matching to the eBay link above.

The other cel is up for 10000yen.  I only looked 
at one of your links for the CCS cel, but the 
seller is different from the SM.

Bah... I can't think on 5 hours of sleep.  >_o
