Well based on the name of the course I would say he is over hyping tax sales. Tax sale Gurus are common and they usually use the Pennies on the dollar pitch for their courses.
However it seems to be priced right. Ned's rule of Gurus states "The value of the information you get from a guru or course is inversely proportional to the price" based on that It's probably good info.
If you do get it please report back here what you think. People often ask me about tax sale courses and I would love to have something to recommend.
