Look guys, there is a HUGE markup on scuba gear just like there is on many types of sporting and leisure activity equipment. HUGE markup. The LDS simply refuse to discount and as a result they are going under--one by one. Most charge absolute full retail. I refuse to pay full retail to anybody--period. They have many of you snowed with all this super critical and life support and blah blah mumbo jumbo. This scuba stuff is largely simple and mass produced and often marketed under a variety of labels with minor changes with HUGE markup. The 600 dollars for a molded plastic regulator is BS even if it is Apeks or whatever----it is a molded piece of plastic with a few other plastic and silicone molded parts, probably about 50 dollars worth of stuff plus another hundred in manufacturing costs--the rest is profit to everyone along the way from the big plant that produces all this crap right on to when the LDS charges you full retail markup--why---because you will pay it and smile doing it because it is life support equipment.
