GTO is awesome. I watched it from the beginning with English subtitles. I prefer to watch them in Japanese. More authentic. Try looking around from eBay, they usually have some rather good stuff.
Haven't had much time watching anime with the kids and all but the most recent one I've watched is Graveyard of the Fireflies. Good stuff. Will make you weep.
Another anime series that's good: check out Hellsing.... but uhm.... you're a minor. Are you sure you're able to watch?
In any case, don't tell anyone I recommend that.
