Cels Forum

Heh, some of these series are hardly obscure IMO. 
Maybe they are in the US but not in Japan!
Cyber Formula is rather popular. There have been 3 or 4
OVA series, each a good 8 eps long, there was the TV series
which ran for numerous seasons.
Few GW cels leave Japan due to rabid fangirls(although I had
a few including a really nice Heero which I sold on ebay
but had to relist a few times since it seriously didn't get
any bids even though thes starting price was more than 
resonable.)
Same reason applies to Saint Seiya-I know there are a LOT
of Saint Seiya collectors in Japan!

On your list, the only things I could see as being obscure
in the US, Japan or anywhere is the Ys cels(they're old and
probably destroyed) and Fire Emblem(the game this was based
off has a rabid following.)

I know how you feel tho, I have some rather off-the-wall
tastes myself.  

Pharna,

characters whos names no one will be able to pronounce from
