ScottZeagle:You can call this a Zeagle problem if you would like, Scott
Thank you for the reply Scott. I don't think that this is just a Zeagle problem at all. From the above posts only DiveRite apparently will sell kits and manuals to end users (which I don't personally know iif it's true or not). Everyone else doesn't although then it becomes the question of whether it's possible to get the parts/information through other channels - and often it is if you look very hard.
I understand very well that all the legal issues need to be clear, so again, I'm simply discussing - not moaning.
In the end I also believe that even if parts kits were available from manufacturers so people had a choice, it would still only be a few who actually did it - and the vast majority would still prefer to let a technician do it. Of course the other benefit for those who service their own gear is that they will also have a far better understanding of their own equipment than the average diver who just knows that that's what you get your air from underwater. I do a few simple checks before I go on any trips. Stick a pressure gauge onto my inflater hose and check the IP. Pressurize the regs, then turn the air off and check back an hour later to make sure the pressure didn't drop. Of course it then helps to know what to do about it if these would detect any problems! (I also take rebuild kits with me in my save-a-dive box! )
