I had already purchased the Starting an eBay Business for Dummies book so I was very skeptical about purchasing this book. I decided to just read parts of it in the store. I ended up buying it because I liked the style of his writing, and chapter 4 on tips for serious sellers really hit home. He talks about not getting too wrapped up in each individual sale, that for a serious seller it is important to do a volume of business. He also puts importance on the professional design of your ads, a logo, business cards, etc. to let people know you are a serious professional. I haven't read the book cover to cover but a lot of his information is to the point, with great stories on established eBay sellers and their different approaches. This book is also more up to date than the Dummies book, and talks about PayPal and its pros and cons in detail. Overall, this is a very useful book with great information, and I might not have purchased the Dummies book if this had been out before.
