Especially for someone just beginning to go through this, this book, like most of the Dummies books, was a good, if somewhat plodding in a couple of places, introduction. It tends to say the same things, or at least very similar things, in various places because a lot of the things you should look for and do remain the same in various situation. However, there is a lot of value in breaking things down in small parts and going through things methodically. This book does that.
