"Trance-Formations" is a good book, but I wouldn't pay $70.00 for it. IMO "Training Trances" is a better deal, the book itself is more to the point than "Trance-Formations." "Trancework" only cost me $40.00 and it is a much larger book, and there are two other large Ericksonian textbooks for under $70.00, "Ericksonian Approaches" by Rubin Battino and "Therapeutic Trances" by Stephen G. Gilligan. I haven't read on bought these two yet(They are certainly on my list,) so I can't fully recommend them but they both have good reviews, and Gilligan is usually considered Erickson's top student.
