Sorry but there are two books that seem to be the same thing. One is more expensive and is out of print.
Amazon.com: E-Myth: Michael E. Gerber: Books
This one is now in print and seems to be the latest but has the word added "revisited".
Amazon.com: The E-Myth Revisited: Why Most Small Businesses Don't Work and What to Do About It: Michael E. Gerber: Books
Since it is cheaper I am wondering if it is a condensed version or different a lot from the original or....???
Should I go for a used copy of the original or is the revisited copy the latest version of the original?
