Getting started in kettlebell training

[jqmaverick]

I'm seriously considering getting started in it.
So what does a beginner need?
I was told a 16kg kettlebell and "Enter the Kettlebell" by pavel.

Is this the best book on kettlebell training? Is it complete on it's own? (I've heard you have to buy "power to the people" to go with it.)

Is the one kettlebell enough? or will I end up having to buy several?

Thanks
