Ranma 1/2 is definitely a good choice. It is a little old but it is still very funny. Has romance and a bit of action as well.

[The story revolves around a 16-year old boy named Ranma Saotome who was trained from early childhood in martial arts. As a result of an accident during a training journey, he is cursed to become a girl when splashed with cold water, but hot water will change him back into a boy.] -Wikipedia

I really want to tell you more about the story, but I don't want to spoil anything. Don't worry, the art and effects get better throughout the series. And if you are familiar with the awesome anime Inuyasha: A Feudal Fairytale, then you would notice that in both English and Japanese, many of the voices are the same in both shows.

The music for the show is pretty epic too. I think you would really enjoy it, or I hope you do, anyways. Have fun! :3

All I can think of at the top of my head are:

1) Hana-Kimi - Manga, Live Action Series (Japanese, Taiwanese, and now Korean)

2) Power!! (na: Girl Got Game) - Manga

Unfortunately these have never been animated. : ( But I absolutely love Power!! and it never gets old!

I hope that helped a little.
