samurai 7 and cowboy bebop are great choices.

ken akamatsu has several romantic comedies if that so intrigues you

as a starter, read (there is no anime for this) A.I. Love You. His shortest work (only 8 books).
after that, Love Hina, the anime and manga are both fantastic, and by far my favorite series ever.
then negima, a great (albiet somewhat long and incomplete at the moment). the manga is far better then the anime, but the anime is also good.

if romantic comidies are not your style, try gunslinger girl. good action and builds characters that one truly begins to care about.

another one to try is samurai shamploo. i own all the manga and the dvd box set. the anime is better, but the manga is also good. great action in 1700's japan, with a hip hop beat.

and before i go, do not read the cowboy bebop manga, it is horrible...
