I would guess that any of these courses are good. The problem is not the training. It is getting a manufacturer to recognize it and sell you the parts! Currently to my knowledge the only ones who will do this or allow their dealers to do it officially are HOG/Edge, Dive Rite, and Zeagle(and they seem to have gone back and forth on this- what is the word now Scott). All others have an "official" policy of requiring you to take your regs to a dealer. We all know that is often overlooked by those dealers who recognize that there are people out there who can and do service their own and will sell you parts for any reg.
The problem is that in some cases if the mfg finds out they will be pricks and threaten those dealers or even pull their dealership. For those who are offering the courses, and Dale I'm sure yours is a good one, what mfg's support it and will sell me kits once I'm done with your class? This is the reason that I have a two year goal of replacing all my regs with HOG/Edge. It will take me that long cause I have 6 more to go after already buying two.
