Their pricing seems comparable, have you had a chance to visit the website?
From reviews, everyone that has taken the course highly recommends it and states that the instructor is "fair, but tough". I get the impression it is run the "right way". I am actually signed up to attend the Basic Riders Course in a few weekends.
I did email the company, got a response a few days later but it didn't necessarily address all of my concerns. So that was disappointing.
