I wrote a hub about the Super Affiliates Handbook last month, it is possible to get it cheaper if you hunt around long and hard enough.
I have a copy and my opinion is that overall, the book was written a number of years ago - and has been regularly updated since - and it does start with the basics and go all the way through things you need to do/know, but there is a lot of waffle in it too.
It gives a good grounding of the basics, but there's something new to learn every day so no one book could keep on top of current trends and emerging technologies.
I do sometimes flick through the Super Affiliates Handbook just to dip in and out to see if it reminds me of anything I could or should do, or if there's anything that I know works and had just forgotten about.
All the information is available free on the Internet, so it just depends how long you have available to get up to speed. There are things I learn still every day - and if I stop learning something new every day then there must be something wrong because you can never stop learning how to write, build your web presence, promote products or promote your own website, product or services.
Hubpages can give you everything you really need to know, I guess the purpose of a book like this Handbook is to deliver the information in a chapter format, so you know when you are at the beginning and the end. Looking things up online can often just mean you're grabbing pieces of a jigsaw, but you're not sure how (or if) they fit together, or even if the pieces you have are from the same jigsaw.
