I found an online copy of Silent Knight Sho today (the one Kurumada drew after Saint Seiya, but never finished after 2 volumes.) Unfortunately, it's in Chinese...
But, er, if you click the buttons at the bottom, you can see the art work... Or if you can read Chinese, there's the complete manga. It's also got Saint Seiya G... Ick, what's the matter with that art?! (5 volumes)
Oh, and of course all 45 volumes of Saint Seiya... It also has free Hellsing, Ranma, CLAMP, you name it... Guess what I'll be doing all day. This is really bad... Really, really bad...
