outlaw star is a pretty classic anime. lately i've been into more slice of life and humor anime though. for humor watch minami-ke 1 and 2, sayonara zetsubou sensei 1 and 2, lucky star and Hayate no Gotoku. i found all of them to be hilariously funny(if you've never seen lucky star, you should watch it). downside is that minami-ke 2 and sayonara zetsubou sensei 2(quite a bit of talking, but there's a lot of one liners) are currently ongoing. spice and wolf is another very good one that i've fallen into lately, they've only got 4 episodes so far but its quite good it seems.
there's also macross if your looking for space types. dont bother with robotech because its based off of macross and two other stories. the first ever is the super dimension fortress macross(full given name), then theres macross 2012: do you remember the love?, then macross 2, macross plus, macross 7(with ova's and movie), and the newest one is macross F(or Frontier) which is only on its second episode soon. so far it seems pretty good and it has yoko kanno doing the soundtrack as well. for those of you who dont know, yoko kanno did the soundtrack to macross plus and cowboy bebop and some other series's i haven't heard of.
