Saint Seiya Manga

Hi,
I'm searching for everything around this manga.
It's a bit difficult, as it seems it wasn't that popular in the english world.
MangaTraders and others seem to have only some chapters, but not the whole series.

I know this is a bit of archeology, as this manga started many years ago, yet if someone knows of places where I can find these antiques, I would be very grateful.

Edit: Forgot to mention what I have as of yet:
Nankh seems to have scanlated some volumes
WAC also
I hope to find more

Lurk shows that V19- V28 were scanned by [SS-HMS].
I don't know about the previous ones, if you find it, we might take it to the next round of gotwoot readers.

So I'm trying to sum-up the stories we're searching for:

Original story: (starting in 1986!)

• The Sanctuary Arc
• The Posseidon Arc
• The Hades Arc

Alternate:

• Episode G

Prequels:

• Lost Canvas
• Next Dimension

I Found Lost canvas, scanlated in French. I wonder if I'll read it..

For the Prequels, it's funny to see that there are two stories happenig in the same era (though dates differ, stories happen in the same chronology). I wonder
why they do this.

Edit:
thanks for the #Lurk idea, didn't know at first what it was (although I knew IRC related) and Google helped a lot finding an interresting website... It seems most of the vintage are missing, but it a very nice start. Thanks a lot.
