Hi Robert,
Symantec does not sell any self study books. Rather, we encourage candidate's to take the training; however, as you listed, it's out of your price range. I'd like to encourage you to check out the exam details page at the following link:
Stay tuned to the link above, as early next week we will publish a study guide that maps the exam objectives to the course lessons and topics.
Also, since you mentioned below that you have several hours of lab experience, you can rest assured that we recommend a minimum of 6 months field experience to help in passing the exam. This exam was developed with a good portion of real world scenario questions that aren't covered in the course materials. Instead, the real world scenario questions are based on field application using the product, as well as the product documentation. Therefore, you might have a real good shot at passing based on experience. Nonetheless, I would also encourage you to look into other areas of self study listed on the Web page from the link above. There you will find links to helpful websites and our new Symantec Backup Exec Tech Center Modules.
I hope this helps.
Beverly~
