I got both Secrets of the Poser Experts and Practical Poser 7 and I'd recommend the later in a heartbeat! Very useful book. Secrets isn't bad either, but I consider it more of a source of inspiration than a book I can actually learn about Poser from. Focuses quite a lot on postwork and I didn't really need any Photoshop info. As an inspirational piece though, it rocks! Practical Poser 7 on the other hand, contains a lot of tutorials and information that you'll very likely put to use immediately.
