Has anyone had either direct or secondhand experience with ETA Programs, like a Codie Sanchez's 'Contrarian Thinking' or Ben Kelly's Acquisition Ace? I had some introductory calls with them some time ago to kick the tires, but didn't end up following through for a whole host of reasons.

Just wanted to see if anyone has had any experience/success/failure with these types of programs and would be willing to share their thought process.
