For a first gun, Kibler IS the way to go. It will teach them the basics of inletting, drilling and pinning, drilling and tapping, proper architecture,etc., without the need to pull your hair out.
It will prepare them for the real deal later if they want to try it.
I live in Mesa, AZ in the winter as well.
If you don't already know, there are several ML clubs in the area with monthly shoots.
Please feel free to contact me if you'd like to learn more.
