CSS Web Design Books, part II

Back in September 2004, I purchased three CSS books, although I don't regret buying any of them, I'm still looking for the perfect practical CSS book. Slashdot just posted a positive review of Web Designers' Reference: An Integrated Approach to Web Design with XHTML and CSS which is rated 5-stars and has a sales rank of #356 on Amazon. Another Slashdotter, recommends Web Standards Solutions: The Markup and Style Handbook which also looks interesting. Do any of my many, CSS-savvy readers have any comments on these books?
