www.animesuki.com - You type in what you're looking for, and so long as it's not licensed in the U.S. and someone has subs available on the Internet, it'll show you where to find the torrents.

Also, this LJ community (http://community.livejournal.com/anime_downloads/profile) is ridiculously active in uploading and providing links to episode downloads on sites such as Megaupload.com.

So far, Romeo x Juliet is only subbed through episode 2. The RAW of 3 was released yesterday, I think, so hopefully the sub is not too far away.
