We do have an anime thread, so you really should post there...

On the other hand, this is kind of a specific topic, so I'll let it slide. I'm thinking about killing the Anime thread though, it's just too general.
Anyway, check out Black Lagoon. It's 26 episodes, but it's a whole bunch of smaller arcs thrown together without a huge overarching plotline. You can stop after any of the story arcs (though I don't know why you'd want to, it's very good).
