Samurai Champloo, Cowboy Bebop, Claymore, Gundam Wing/Seed/00 (Seed's really overrated though), Full Metal Panic and it's 2 sequels, Monster (if you liked death and code geass mess with your head style anime), Trigun (horrible ending though), Chrno Crusade, Wolf's Rain, Fate/Stay Night.
Not all action anime, but still very entertaining.
