I purchased the ebook for the 2500, and it was alright, I mean I have spent 40 bucks on worse things before! Well to get to the meat of your question, he covers a lot of things in there, but they are things that you could discover on your own with a bit of trial and error, or for that matter just messing with it for a month or two!!
If you are new to the MPC, then I would recommend it, if not then you probably know everything in the ebook already.
