Query: Waste of money!

If you're considering purchasing this book from Amazon, you obviously have internet access, and believe me, the information in this book can be found online WITH MUCH GREATER DETAIL than what you'll find in this book!All it is, is a bunch of computer generated images of TYPICAL hydraulic setups. I stress the word "typical," because it taught me nothing new. This coming from a white boy that was a Hydraulic newbie at the time!Don't get me started on the choice of font used throughout the book and the GIGANTIC size of it! Its a joke...as if it was written by, and for, children!Spend some time on layitlowdotcom and you'll learn EVERYTHING you need to know, FOR FREE! Layitlow is an awesome and helpful community of peers, most of which are very experienced.Seriously, I was disappointed with this book. I regret this purchase.
