The weekly podcast that he does is also very good.
I also like the GunTalk Radio podcast (http://guntalk.com/site.php) that Tom Gresham is doing. He also just started GunTalk TV (http://www.guntalk.tv/site.php) that is loaded with instructional videos. Many are free but he has a $5/month subscription to watch them all. He is hoping to have several hundred videos by the end of the year.
