Anyone have experience with callwriter.com?

I watched an informative webinar today by callwriter.com. Has anyone read this guy's book:

http://www.amazon.com/John-Brashers...1_fkmr3_1?ie=UTF8&qid=1263964185&sr=8-1-fkmr3

or subscribed to his website:

If so, I would appreciate your opinion. Thanks.
