Manga Style - One of the BEST Sailor Moon Sites on the web. It is very similar to SG & BSSMG
Moon Feathers.com - This is a really cute site. I enjoy the Java Applets that she has.
Lycentia's SM Web Graphics Shop - For beginner site makers that need a little inspiration, this is the place to go. Lots and lots of graphics. Some are a little...cheesy (no offence), something that a professional site wouldn't have on it.
Sailor Moon Romance - All I can say is "beautiful"
