I'm still a major fan of www.seoonlinesolutions.com . seoonlinesolutions in particular always seem to work hard to ensure quality to their own standards. I've never been a fan of any 'guide' that is really just another vessel for paid advertising though. Those that charge for inclusion, which notably includes SEMPO, are always biased, and not helping the industry or consumer at large as much as attempting to help their own coffers.
