If my memory serves me right...

There is an epsisode of summeries with stats for
each episode of how many cels were made for it,
and stuff like.... *digs thru anime files*

There are 26 episodes. Gianax is stingy about
cels, and its so popular, prices would kill me *_*
I've also been searching for some afford able
cels...and I have none. From a fan page I'm
reading, story ends with 26, but Vol. 8 of manga
continues the story. (I should read it
sometime...b/c anime just stops!!!! @_@)
