"There is usualy not a renew of interest for the
older anime. Only for cels from the older anime."

Yes, that is what I've been discussing, when did I
say there has been a renewed interest in the
Dangaioh OVA series itself? I did not even mention
anything about cels from the crappy new series.
I've talking about the cels from the original
Dangaoih OVA and how I disagree with you about how
there has NOT been a renewed interest in the
series. The prices have increased within the past
two half years, considering the time period IMO it
is not "sudden". 

Morevoer, I am not making any assumptions as you
incorrectly claim Yann about this, b/c I know for
a fact that I am usually one of the two final
bidders. And I too have been collecting back in
the period when YJP had cels from this series well
below 8k; you are not the only collector of this
series. But you would be hardpressed to find any
nowadays at reasonable prices.

Lastly, while you may consider the cels, "...on
Yahoo Japan... good. But not better than those
available before.", isn't this natural? Doesn't
that go without saying?! Most things were cheaper
years ago. Can you find high end BGC OVA or
Dangaioh OVA cels for the prices that "use to sell
years ago"?! Sheesh. It is only -natural- that the
prices do not remain the same. Considering there
is not that much available to begin with anywhere,
I for one would love to read your suggestion on
sites you can list that have equalor better
quality. I doubt you can, especially if it is not
on already on YJP. Thats all I am saying about this.
