what are some good manga

I'm looking for some easy to read japanese manga. my kanji knowledge is about 600 characters and my vocabulary knowledge is about 3000 words or so. I enjoyed yotsubato, ichigo mashimaro, azumanga daioh, i.e. light-hearted slice-of-life comedy. can you recommend any other manga series like that, that's not too difficult to read.

thanks
