Before spending loads of cash on any investing system, I would recommend visiting ebay and trying to pick up a inexpensive course that is within the niche that you are interested in. I have purchased several real estate investing courses from Ebay at a big discount.
Tim Mai is not the only one with this system. There are similar systems advertised by Jeff Adams, Larry Goins, Joe Crump, just to name a few of the advertisers that flood my email inbox. I am sure there are others with comparable systems.
