I bought his book and found it to be the answer to 90% of my questions the other 10% has come from this board. Actually his book has a little more information but this link has a tremendous amount of his book content and color pics as well. Not trying to take away from his book revenues but this will help those who haven't been able to find it.

Cheers... SB
