I have worked part time as a rifle instructor for Front Sight's practical rifle courses, and have been a member for several years. I've taken numerous courses over the years, and have found over 95% of the stuff I learned (and taught) to be sound, universal and reasonable.
The catch with Front Sight is mainly that new-to-Front-Sight students can only attend the basic level courses, and the best stuff is kept at the higher levels. The reasoning for this is sound - they train so many people in the basic classes that really have never been trained before. But on occasion, there's a higher-speed person that gets bummed out that they're shunted into a beginner's level class, and they get turned off. Anyway, neither as a part time staff member, nor as a student have I ever heard anyone come across as less than professional. They work with what you bring, and they generally hit their goal of turning you into a better shooter. Some folks are already far beyond their basic classes, though, and if you're one of those, realize that it's an extra trip out there to show them that you have the skills to move on.
I would recommend Front Sight to anyone who lives close to Southern Nevada and has the funds for the class. If you're all the way across the country, there might be more economical training for you in your area, but it probably won't be as consistent as that offered at Front Sight.
FWIW
