The Kindle edition of Gordon McComb's "Must Have" book is only $1.21? http://www.amazon.com/Robot-Builders-Bonanza-4th-Edition-ebook/dp/B005K8H1FE/ This awesome book belongs on every roboticist's shelf and Kindle. I have a signed hard copy from the master himself, but you can bet your bot I will add this to my Kindle ASAP. The hardcopy is worth every penny of its still-$20.22 price, it's hard to believe this paltry eBook's price isn't a mistake. Just to be safe, nab one quick before Space-happy Jeff Bezos comes to his senses. Sir Gordon posted this jaw-dropper himself in the Parallax forum. http://forums.parallax.com/discussion/162933/my-books-cheap#latest where he mentions his tiny royalty. Anyone who gets this eBook should just mail Gordon a dollar. He is a giant among roboticists and a real gentleman.
