Not true, just because the "LDS" doee not stock the Conshelf does not mean they do not have the parts, the Conshef first is a generic Aqua Lung unit, external appearence varies but many of the internal parts swap between models. It is the most simple of first stage designs, has been around forever and parts are everywhere any Aqua Lung product can be serviced. It is simply a fact.
Conshelf for example:

and compare to Titan:
Titan 1st Stage Service Manual - Page %CURPAGENUM% of %LASTPAGENUM%
The second stage seat is a generic piece, common to a variety of models, it is just a very simple regulator to repair and service. There are legit reasons some might prefer a different model but lack of parts is not one of them. Hope this is helpful.
