I'm in a similar boat to OP, with the added wrinkle that my son has started diving and potentially one or two of the other kids may start.
My wife and I currently have 20 yo. Oceanic regs, with the infamous "puck" octo which started disintegrating, and which our LDS charged about $300 to disassemble, determine they could not get parts, and then reassembly only my wifes reg now breathes too hard. We figured we'd buy new gear for our 20th anniversary and an upcoming "big trip," but the LDS sells Aqualung and associated brands, and I don't want to go down that road as the company seems to be in trouble.
I looked at Scubapro at another shop, and acquisition/service costs aside, I wonder about convenience and whether the shop would put the time and attention into service that the manufacturer or I would. I've been "in back" at a couple of shops and was not impressed with the service areas. The organization and care certainly don't match the mythology about "critical life support equipment" and "it's nearly rocket surgery best left to professionals."
This all has me leaning heavily towards Deep6. I like that I can just throw them in a box and ship them off where the manufacturer presumably has their stuff together and an incentive to keep the reg performing well, versus driving to the LDS for an indeterminate wait and unknown cost. I also have the option to get DIY, with manuf support, for the price of a course if I decide to take that on, which starts to make more sense if I have 3+ sets to service.
I am so sorry you had to exprience this
Y'all need need a right to repair revloution in the US, it's happening but slow -- and it's not really trickling down to Scuba gear.
I am not saying it's all fine and dandy in EU, but.. even SP (or their dealers) can't pull something like that over here
this is not strictly regulators, so forgive me being out of forum, but the sentiment still holds:
in January I got a G2HUD computer from ebay; when it arrived it was in dead mode.
I wrote SP and they told me all I had to do is drop it at an affiliated shop around me.
They shop forwarded it SP, they revived it out of deep sleep mode, contacted me for pickup, and charged me 20€ for round trip shipping to Uwatec (switzerland) where it got fixed.
Now mind you I am not the original owner of that computer; none of them were under any legal obligation to honor warranty/service agreements.
Now with regards to regs, they still want you to go through their affiliated authorized dealers; but service kits are available to the public (via retailers not via SP dealers, equivelants in US are DGX and DRIS maybe); so you can still go to a 3rd party or DIY it without crossing into a grey area or putting a shop owner in a tight spot.
Not perfect, but it works -- I buy my kits and do it at home; and the SP authorized dealers (and LDS) rent me the tanks I need knowing I will use that air to tune and check what I just serviced.
If it wasn't for the lack of EU true presence -- and some appreciation on my side for some older SP models -- I would have also been a D6 user; and the next
new reg set I aquire probably will be from a company like that (I am already considering a few of the new ScubaGaskets MK10 clone)
But my next reg will probably be an old SP one that I find on some classifieds ad.
