I bought this book out of curiosity even though I have a well-equipped shop. Looking back at almost 15 years of random tool purchases, I'd say that many people like me end up having a lop-sided set of tools. For example, I have lots of power tools but my first decent bench came together only 2-3 years ago. I have four corded and four cordless drill/drivers, but some essential small tools suggested in this book are missing.
With the benefit of hindsight I'd say that it is more important to have a wide array of the right things, rather than few high-end things. To that extent, this book is right on and a good place to start if you are setting up your (first) shop.
Now I await the sequel to this book "...now that you have finally set up your first shop, The Shop you really want to have and why". You know, the one with all the cool tools and set up. Seriously, I'd like to see a shop book that tells you about the higher-end version of every item it suggests. That said, I do realize that the preceding approach would create an intimidating atmosphere for the builder of the first shop rather than the inviting, simplifying, and "you-can-do-it" approach of this book. Overall, this book is a job well done and will serve a first-time shop builder well.
