well such general request are hard to answer. First series with those elements that comes to my mind is
Maison Ikkoku (great series btw).
Personally, I look for new series by browsing through
AniDB. For example choose one or two categories and sort these series by rating,look at the picture, read the description and perhaps some reviews.
Now that I think about it, the other Rumiko Takahashi series like
Ranma 1/2 and
Urusai Yatsura fit your description even better.
