Several months ago I could only afford one book on web design when I got started again after a couple year layoff. I use an older version of Dreamweaver which isn't kid stuff but isn't bleeding edge either.
This book is well written and designed and made it easy for me to understand the basic concepts that I had either forgotten or blew off because they gave me brain freeze in the past. Great use of color and plenty of examples to both show you how to do stuff and give you ideas for your own site.
Not for you if you're already advanced, but if you have a little knowledge and want to get yourself up to speed, this is a great choice.
