- You don't want to spend money.
- You just want to read text, not listen to lectures.

Truthfully, the products are not mutually exclusive–by all means, read the FS Basics of Scripting and the FS Development Network documentation. Realize that the Basics of Scripting documentation does not include documentation regarding the latest features such as collections and arrays, but it is a very good introductory text. The FSDN is very important, and in fact my materials discuss in depth how to use it to its greatest advantage.
