Since bunghole and I already have our CHLs, I think he was talking more about taking TDSA's Advanced Pistol I class. Take a look [url=www.tdsa.net/course.html]HERE[/url] for course descriptions.
I took the class originally two years ago, and have since gone back again with my wife. The nice thing is that once you've paid full price for it, you can go back and audit the class anytime there's an open seat for only $50.
