There is an audible version of 'Stock Operator' and it is great to listen on the ipod when stuck at an airport. I learn something new each time I play it. http://www.audible.com/adbl/site/pr...p?productID=BK_RECO_001172&BV_UseBVCookie=Yes (Sign up for a trial to get it much cheaper!) Enjoy!
Even with the PDF downloadability and podcasts everyone should consider buying a real copy. This book is one of the FEW that is so worth the cover price. I would suggest to just buy it and add it to your library. It never gets outdated and I always find myself picking it back up for another read. I'll always find a new bit of enlightening information that went over my head in the past.
