I have the audio sets "Unlimited Power" and "Personal Power" as well as the books "Unlimited Power" and "Awaken the Giant Within." Tony's best products he has are the "Unlimited Power" book and 6-tape audio set. "Personal Power" is full of fluff IMO.
I'll second the Essential-Skills products and training by Tom and Kim. They are the best I've seen in teaching how to anchor other people in non-therapy situations.
Another good source is Ross Jeffries. Even if you have no interest at all in seduction his material for personal change and communications if far ahead of what Tony teaches.
For learning therapy from what I've heard NLP Comprehensive is one of the best sources. They also have a book and audio series in the introductory/general success catagory, "NLP: The New Technology of Achievement."
