Read a few myself, Berserk, Black Lagoon and Hellsing come to mind. Mainly Berserk at the moment though, trying to catch up to where it is now, though it'll take time consdering i'm only on volume 13. Hellsing wise, i've watched some of the original series, but have kinda left it, what with ultimate meant to be better and the manga obviously more so. Black Lagoon i'm up to date with both anime and manga wise, really good series overall, and personally i can't wait to see the 3rd season of it when its released..though when that is yet to be seen.
