What do you mean by 'kind of'?
The Conshelf XIV is still in the books (more specifically the catalogs) as a current production regulator, but it is so pricey that I doubt many have been sold in the last decade or more to the general public.
The Navy (ours and others) and commercial divers are probably the only real market for the present production of Conshelf XIV. And IMO, that market is probably so small that it probably is a very limited production. I may be wrong I hope that I am.
There are so many used Conshelf XIV out for sell, in excellent condition, that IMO very few people would really be interested on paying for a new one (if it was coming out of their own wallet).
The Conshelf XIV has been in production literally for decades and it has changed very little. It is a great regulator.
