archman:'Cuz it's COOL boogie! The gearhead (or techno-nerd) population is indeed a mighty demographic in diving. Any miniscule reason to buy newer and better stuff... I'm feeling the shakes just thinking about titanium. MUST RESIST!
Yep, the snob and/or geek factor is about 90% of the appeal for some customers. I had a customer come in the other day and go on and on about his $1200 MK 25T and get all concerned about whether I had the parts to service his extra special regulator. I assured him I had a kit designed just for his reg and then aftter he left I dug out one of the 50 or so Mk 25 kits in the bin and rebuilt his reg.
His MK 25T will do absolutely nothing that a standard Mk 25 can't do just as well (but a standard Mk 25 can pass a tank of 100% O2 at 3500 PSI that would leave his reg at risk of going up in flames.)
But the important thing is that it makes him happy as he paid 3 times what he would have paid for a regular Mk 25 and is extremely proud of the fact that hardly anyone else has the lack of sense required to buy one of their own. Consequently his reg is pretty rare and provides him with the opportunity to impress all his poor captive companions on the dive boat.
The Mk 25UL and MK 25T are great regs from a sales standpoint as price is part of the appeal so we never have to even think of discounting the price on them so much as a penny.
I had a Mk 25 UL come in for its first annual service this spring and it still had the slightly worse for wear price tag stuck on it. Apparently he was modest and did not want to actually have to brag about how much he paid for it ($938) but rather preferred to just let people see the tag for themselves. It takes all kinds to make a world.
