My personal favourites: (begins with the best)
One Piece
Battle Angel Alita
Yakitate Japan! - awsome manga about bread ;p
Dragon Ballz
Ranma 1/2
Bleach
Deathnote
HunterXHunter
Psychic academy ;P
Girl Saurus - a guy which is ridiculously afraid of woman since he was nearly beaten to death by a once fat woman.


Well, Im also kind of looking for new good/funny manga to read.
