I created an X-Ways Forensics online training course at http://courses.dfironlinetraining.com/x-ways-forensics-practitioners-guide. This course, X-Ways Forensics Practitioner's Guide Online I is introductory to using X-Ways Forensics, but it covers more than enough to cover most of the use of X-Ways in a case.
The XWF II course goes into great detail with more information on using XWF in different scenarios and some more highly specific functions. Although the course is based on the book, it is not the book, nor is it the X-Ways Forensics classroom training. It is however, the least expensive and fastest way to get up to speed on X-Ways Forensics :)
There is a 25% discount code you can use "xwf1" that is good until July 17. Everyone that registers before July 17 receives a separate discount code of 100% for the XWF II online course that will be released as soon as this discount period ends. Both courses are the same cost, but the discount is valid only until July 17.
If you can't attend the X-Ways AG classroom training due to cost or time, this online training fits both your pocketbook and daily schedule.
