I have a lot of the AGI courses on DVD also, the instructor is very knowledgeable but extremely boring. If you enjoy Ben Stein in Ferris Bueller's Day Off then these videos are right up your alley,
Have a cup of coffee, walk outside when it is -20C for 5 minutes, run inside and try to stay awake during the video. Some of the other videos have other instructors and difference is night and day to the boredom factor.
Camera work is good to poor, some shots are from I swear 20 feet away and the guy is trying to show you how to install a carrier spring in a shotgun, that is if your eyes are still open.
Like others have said , how much are you really going to learn from a video. You will be able to take apart the firearm and reassemble it and check for wear. Do you honesty think you can lighten a trigger on a 1911 watching a video?
Can't imagine there whole gunsmith course is made up of material that is new and not covered in these dvd's.
Only reason I have the DVD's is a bought them in the US at a pawn shop for really cheap.
