Also it may be that some of the collectors haven't seen
the scenes yet and do not know what they are seeing. They 
have only released the firt 30 or 32(??)Tv episodes in the
US. Unless someone has seen the subs they may not be aware
of what is Tv and what is OVA. Many people are looking for 
Tv Tamahome, I have seen quite a few very nice cels of him
recently that are from the last Tv eps but don't even sell.
This could be especially confusing with Taro where many of 
the Tv cels are listed as OVA and vice versa. For ex. All
of those white tuxedo tamahome cels are from a special
scene (the Dream sequence. I thought it looked more like a 
near death experience personally. I am probably looking to 
much into it ^^;) in one of the last episodes.

I also agree and am VERY happy that FY cels are alot cheaper
then they have been in the past ^_^. 
I just started collecting the series, it is good timing for 
me. It seems like alot of the really nice cels are in 
collections now but they probably would have been too much
for me anyways. It saves me some of the torture of getting
to a site right after an update and seeing an amazing cel I
can't afford despite it being worth the price. (ACHIKA AT VEGA >_
