Mandarake has some Evangelion cels.  (I've never
even seen the series, but I recall seeing the
cels on their website...)

They have a set of Eva opening cels, and also
one of Misato... I thought they had an Asuka cel
or two as well, but they may just not be posted
to the site...

(You have to click the "New Items" link and
go through the pages to find them...)
