Query: Very inspiring for beginners

This is a pretty good "how to" book. However, if you've been selling at all on ebay, there's not a whole lot of "secret" left to much of the text - a lot of it I had figured out on my own through trial and error. If you haven't sold much on ebay, the PowerSellers success stories will definitely be inspiring. For more advanced ebay sellers, I'd suggest "The 7 essential steps to successful ebay marketing"- I picked up a copy the other day, and read it in a night! It's more of a strategy book than a "tip" book and I'm confident that it's going to help me earn more money with my ebay business.
