Here are a few sites that I would recommend...

The Daniel Collection is a fantastic site showcasing and supporting Woodturners.

Allied to this site is one for the Association of Woodturners of Great Britain Seminar's Instant Gallery, this shows the best of this years exhibits.

A new-ish site on the Wood scene is The Wood Haven and I would recommend that you take a look.
