You can get the book directly from the TGM main office at www.thegolfingmachine.com. There is supposedly a new 7th edition that was promised in early April of this year, but no word if it is shipping yet.
As far as DVD's, there is a wealth of free video in our gallery which you can spend many hours viewing and reviewing. You won't find anything better for that kind of bargain.

I emailed the home office the other day. The reply stated "on or about May 1" for the latest shipping date.
