While I havent used Hammerman myself, I've worked with several people that did get their training with Hammerman, and they liked the fact that Hammerman came to their site and worked with their data (customized what they needed to learn).
While that is advantageous in some situations - if you are looking to really learn Crystal - in and out, its better to go with a formal class NOT inside of your own environment, because then you are pushed to learn all of the little (and not so little) things that you would not necessarily need to know right this minute, but will serve you well as you move forward with Crystal.
