I'm new to Zen Cart and I'm going through all the usual headaches.

I was thinking about buying a book called Zen Cart: Building an Online Store the Zen Way. It's pretty much the only book out there from what I can see.

I've read that version 1.3.5 does things a little differently than earlier versions in terms of file and directory structures. This book covers up to version 1.2 7 or something.

I was wondering if this book would be a good investment? In other words, is this book still relevant to someone who is using the latest Zen Cart version and wants mainly to design a unique look into it? Or would it likely cause me more headaches?

Thanks for the insights and any other book recommendations are appreciated as well.
