I sprung for a subscription to his newsletter and am glad that I did - I really like the fact that he researches and writes the entire thing himself and I usually agree with what he has to say - if I don't, he explains his position well enough that I can follow his reasoning. He's also VERY approachable, which I discovered while still subsribed to the free edition of his newsletter and is one of the reasons I decided to show my support by paying for a full subscription.
