Out Of all the hypnotherapy, stage hypnosis and conversational hypnosis books and course I have bought and found Igor's Conversational Hypnosis Home Study Course and his Private Hypnosis Club are well up there, He keeps closely in tune with ericksonian hypnosis, and presents facts research and practical information in an entertaining manner that is...well.... hypnotic.
I have had the opportunity to speak to him personally on occasion and know him to be a great teacher of hypnosis first hand, so would gladly recommend anything with his name on it.

Hope this helps, and if anyone else has his products / are in his club please let me know
