Best AS book for Flash MX 2004?

I see myself as an intermediate at actionscripting but I want to start to learn the complex stuff I’ve been checking out some books and the Macromedia one sounds good but are there any others? I want the book in a tutorial style.

The book I’m on about is “Macromedia Flash MX 2004 Actionscript: Training from the Source”

Any help would be much appreciated.

Cheers guys
