Stripping the Gurus by Geoffrey Falk is an interesting survey in this vein, albeit covering a previous generation of problematic cults. Gurus like Chogyam Trungpa, Adi Da (or whatever name Franklin Jones was going by at the time), even reaching back to Paramahansa Yogananda and Ramakrishna. His take is perhaps a little juvenile at times, but I think the book is an interesting survey.
