I'm a very late poster to this thread, I know, but wanted to toss in my two-cents.
I have the "Sonar Power!" books going back to Sonar 4, and have always found them to be invaluable to a slow learner like me. Scott walks you through not only the rudimentary processes, but gives you working examples to SHOW you how certain facets work. I am a "show me", not "tell me" type, and - while he never talks down to you - he explains things very well.
I keep my Sonar X1 Power book right alongside my new Sonar X2 power book, because there are still some things about X1 that I have trouble wrapping my brain around.
I have said it before, but I will say it again: there can be no money better spent than investing in Scott's book.
Plus, there are many neat tips and tricks to be gained on his website
