I have the first edition of W Ellis Brown's book... lots of good info, but special tool diagrams and technical data were a bit unfinished IMO.

I've noticed he has released a 2nd Edition now.

Anyone looked at it?
Or know what has changed between the two editions?
All I can find on his site is that it gained quite a few pages now 219pp and has 300+ photos or illustrations... some now in colour!
