I bought this PDF on the recommendation of a friend after I had asked him about texts to improve my games mastering.

I have never played Cyberpunk, and so some of the advice in this book - and indeed the whole tone of it - was a bit of a miss for me. (I can't fault the text for that: I'm just mentioning my personal response to the material.) However, some portions of it are applicable to GMing in a more general sense: the chapters on evoking atmosphere and dealing with PowerGamerz at the table were quite instructive. At a mere $6 you ain't going to break the bank by giving this a shot. IMO if you ain't a Cyberpunk GM then there are better books about being a 1337 GM than this text: Robin Laws' Good Games Mastery for one.

The PDF itself is reasonable for a scanned image version. Not bookmarked.
