Query: Interesting but relatively basic overviews

Easy to read and interesting, but I think the title of this book is deceiveing. Although the book has good info, it is by no means an "advanced" manual for repairing cameras.Many tips and techniques are just overviews, without specific step by step instructions. I was left longing for more detail.I understand that to cover all the cameras listed in total detail would be an enormous and impractical task, I think it would be a better book if it were to focus more specifically and in more detail on one or two cameras.
