Well... I bit just for fun and bought this.
Essentially this guy is selling a Homebrew Guide , more or less, and including the needed software (Except Zelda) "free". According to him, you are paying for the setup guide.
My thoughts: If you are a complete homebrew newbie, and have NO idea how to get started, this guide would work for you. It pretty much takes you by the hand and gets you all setup.
For most of us with some technical know-how, it's not really worth it. All the information in his homebrew manual can be found online for free IF you know where to look.
This is definatly a case of some people seeing "HomebreWare" as a value, and others seeing it as a scam.
