Pro Audio Gear?


Does anyone know of a website similar to AudioGon which deals with pro audio gear? I would like to find a site which deals in used gear. And, one which has a blue book of used prices etc. And, links to manufactuers would be nice as well.
Thanks

I've done some shopping on http://www.digibid.com, i don't think they have a bluebook (haven't been there in a while), and in general the site made me really appreciate audiogon. But they do sell used pro gear.
PS: ProAudio.Net I mention above (The Pro Audio Network) is similar to Audiogon. It has news, articles, classifieds, dealer shopping, reviews, links, and discussion threads (forums).
