I bought a life membership at Front Sight and so far have been there once. Even just for the course that I've taken (Four Day Defensive Handgun), it was well worth the cost and effort. I learned quite a bit about how unprepared I was if I encountered a dangerous situation.
When I can afford to (since I work retail), I plan on going back and taking that course again and additional courses. The instructors are top notch and are very diligent about making your needs met.
I did not participate in any of their land/home deals, so I cannot comment one way or the other. However, I will point out that many real estate developers face legal problems when investors want to pull out at last minute, just before groundbreaking.
