Rhea posted a detailed review of SEO audit tools comparing tools from Web CEO, Alexa Site Audit, Website Grader, Website Auditor and SEOmoz Tools. There is also a recent article at Search Engine Watch on SEO audits and tools you can use to help.

The Sphinn thread on the topic has comments from Jill Whalen & Incredible Help asking why would SEOs use these tools? One asked, “why would we as SEO’s give credence to such tools?”
