Boot camps/training

Anyone know anything about the boot camps or training by David Lindahl, Scott Sheel or Greg Warr?

I know Dave Lindahl and his training is really great. He focuses on Apartment housing, which is a bigger animal than plain residential. Definitely check him out.

Also, Kris Kirschner and Susan Clark out of Atlanta (Autopilot Real Estate) are FABULOUS teachers of “We Buy Houses”. Their systems, and their trainings are top notch.
