I hate to rain on someone's sales picnic but for something as common as key in knob cylinders I do not understand why you need a cut-away to practice picking. Go by a local locksmith shop and become a friend. All (?most) locksmith shops have so many take-out cylinders they often just throw them away. For the price that site wanted for one, you can buy several new cylinders and have a lot more fun.
Nothing is foolproof to a talented fool. Wisdom is not just in determining how to do something, but also includes determining whether it should be done at all.
