Hey Lady ^^
Eikou Den has only been released in Japan 
on VHS and Region 2 DVD so far, but if you're 
interested in purchasing them, you can get 
them from CD Japan  (http://
www.cdjapan.co.jp)

An interesting tidbit is that the Japanese Eikou 
Den DVDs have an English Audio dub track 
on them, so you CAN watch it in English! Bad 
news though - no English subtitles and only 
one episode per DVD. It's worth it though if 
you're really DYING to see it and willing to 
shove out around 30 to 40 bucks per ep, I 
suppose.
