Buy it for $19. Even if your aren't that interested in the topic just one potential insight from that book will make it worth way more than the $19USD.

This sounds naive. Most books have opportunity cost much higher than their added value.

What are you basing that on?

My personal experience. Plus, I quit reading most of books I ever bought, not considering it worth my time (comparing to other activities, or - other books).

And you don't think I have that experience?
