I agree with most of what you say, especially on trust.
But where I disagree is the necessity for a good service technician to be specifically trained on your particular brand of regulator which is practically identical to many others.
I'm not saying it's a necessity. I'm saying that without it, there are two issues:
Will a shop agree to work on something their tech is not trained on? My shop won't.
Do you trust a tech at some random shop at a dive destination, whom you have no prior experience with, and who does not have training on your reg? I agree that if they have training on a similar type of reg, they SHOULD be able to work on a Deep6. So, it's up to the person with a broken reg and a decision to make.
@stuartv I disagree with you.
I don't know whether your jibes about having a service kit is specifically aimed at Deep 6's practice of inclusion of a service kit on purchase.
My comments about the service kit are not a jibe at Deep6. I think it's great that they do that. My comments are simply a response to other posts here on SB (but not necessarily in this thread) touting the benefit of coming with a service kit. Yes, it has some value. I'm only saying that it does not have as much value as I feel like some people suggest.
Posts I have seen make it sound like (to me, anyway) if you have a Deep6 reg and a service kit, and if you have a problem with your reg, then no matter where you are in the world, if it's a dive destination, you should be able to get your reg fixed. I'm just trying to be more realistic about what the true value is of having that service kit. No matter where you are - at home or on a dive trip - you may not be able to find a reg tech at all (because they outsource reg work or maybe just because the reg tech only comes in on Tuesdays to do whatever work has come in). Or you may find one, but they may not be trained on Deep6 and also be unwilling to work on anything they don't have training on (a la my shop). Or, worst of all, they may be willing to work on it, but turn out to be incompetent and make a complete mess of it.
All of these things detract somewhat from the value of having that service kit in your hand. Yes, it's valuable to have. Just not AS VALUABLE (in my mind) as what some poster's make it sound like. It is not a guaranteed silver bullet. The real value really seems to depend on the diver's particular situation. Thus why I am trying to just bring out a full discussion of what the benefits really are. So that the person contemplating a reg purchase can have the most accurate understanding of all the pros and cons and decide for themselves what will be best for him/her.
