I've had mine for over 6 years. got it in a package deal from Sunshine sports mailorder from NYC. First reg I ever bought. Since then I have added a Apeks tx-100 with sealed first, a sherwood blizzard, a maximus, a Zeagle flat head VI with extreme 2nd, US Divers Artic, AGA, Nira, Odin, and a couple others which came and went so quickly I don't remember them. I just looked and I have the tx-100, the neptune with Nira, the blizzard and of course the 400. The reg has been fully rebuilt only once, most trouble I have ever had with it after over 150 dives on it is that sand got trapped inside the adjustment knob, it caused some grinding and made the knob tough to turn, a complete tear down and clean up and she was as good as new. It now has over 300 dive on it and I finally broke down and replaced all the seals in it. This reg is pretty tough and wears like iron but that may be because I really take care of my gear, and look after it like a hawk. But like I said it has always been reliable and the adjustment has always worked perfect, unlike the maximus and especially my TX-100 (apeks was even stumped on that one and ended up giving me a new reg, which is mediocre in my opinion). Worth every penny at 170.
