Oh goodie I am not the only manga reading person in the group!! There are also two other series that I am really into.
The First is Immortal Rain in which Rain is much like Trigun's Vash. The story is that of a tragic hero doomed by their own actions, in this case Rain is condemed to live forever. Like Vash he ends up having a bounty on his head and everyone wants to bring him in dead..or alive. Except he always seems to escape. Of course I have only read three books so far.
The second is Louie the Rune Soldier which is a riot. This guy is the totally opposite of the everyday hero. He's a mage that prefers fist fights and street brawls to magic. He can be a complete moron and one perverted, beer drinking son of gun, but watching him fumble down the path of a would be hero is hilarious.

And for sights to add links too Tamora Pierce's website is pretty awesome. She has some really interesting reading lists availiable to browse through. Also there is this Potter sight that can basically tell you almost everything there is to know about the Potter Universe created by J.K. Rowling. Of course at the moment I am having dinner, thus I too lazy to find and post them here. I'll give them to our wonderful blogmaster about the same time I remember to show her Kenshin.
TTFN

Edited: Okay, I thought I would try to put them on the side bar, but I don't have those magical powers so I am sticking them in here.
