Ursula Le Guin -- S/D, etc.

On the "Introduce" thread, Scott said he wanted to read some Le Guin. I didn't get around to her until a few years ago, and the Earthsea trilogy totally knocked me flat. I guess it's considered "young adult" fiction, but it seems to me that it works on a lot of different levels. I love how spare and allusive her writing is -- she tell a lot more by implication than anything else. But the only other thing I've read is Left Hand of Darkness, which similarly affected me. On the basis of those books, she's becoming one of my favorite writers, genre or elsewise. So, what to read next? (Or if there's anyone who thinks she's an overrated hippie, you can say that too.)
