Has anyone ever heard of or done the Blissborn childbirth classes?

I was intending on using Hypnobabies, but I stumbled across this program last week and I'm considering using it instead. The downside is that the homestudy program costs $100 more than the Hypnobabies homestudy program.

I'm trying to find more testimonials from people who have done it themselves, but since it's a relatively new program I've having a hard time finding Blissborn veterans.
