I guess I should have and put a disclaimer on it. When I bought it, it was around $275. If you have to buy one book and you can spare the change, this is the one. But some of the others will get you going faster.

It depends on what you want to do, This book is deeply focused and considered an academic text, many teach from it. Once the subject matter in this book is mastered you will be a HF professional for sure, but some of the other books can get you up and running faster.

At some point you should consider this book for your bookshelf but it is not a beginners book that is another reason I was hesitant to recommend it.
