I just got my copy of Zheng Gu Tui Na by Tom Bisio and Frank Butler. I am thoroughly impressed with the descriptive detail and logical approach used by the authors. Rationale for the treatment is given, along with a discussion of the regional anatomy. Intent/visualization for each hand maneuver is given which really adds to the depth of technique. Finally, strengthening exercises for the practitioner and qigong exercises are given, along with the rationale as to why they are performed. The photos are clear, the binding is solid... it was pricey, but worth every cent so far. The book seems ideally suited for all levels of practitioners.
