Poker training sites/Ed Miller

Hi everyone,

I wanted to ask a few questions.

Firstly what is everyone's opinion of poker training sites like Pokercoaching.com and there are of course others ? I was thinking of signing up to one but wanted to get an outside opinion of them Does anyone have any opinion of which one of them are the best ? Or if they are value for money ?

Also does anyone have any opinion on the author Ed Miller ? Are his books worth a read.

Thanks in advance.

Kris
