Thank you everyone for your opinions!
I heard of Deep Six, but haven't seen anyone personally who uses them, so I couldn't ask someone for their opinion. From my understanding, Deep Six is very similar to Edge/HOG, where you can service your own regulator. I took a look at their website, it seems the 1st/2nd stage combo for signature is about $380, much more reasonable. I don't mind learning and I consider myself handy, but still afraid I'd mess up the assembly. But the free 1st service is very tempting. How's their regulator compared to Edge/HOG? I remember reading other posts and saw that you also advocate their regulators as well?
From my understanding, sourcing parts for Atomic or Scubapro isn't that easy in the US, and learning to service them is even harder. Do you have any suggestions on where to learn them besides forum? I don't want to learn how to service part that's critical for underwater thru reading other people's comments.
I agree. The 15x seems to a decent entry level regulator set, for being sealed and balanced. And I have no doubt that it will last for more than 2 years if properly cleaned and stored. That's why it makes little sense to spend $100 a year to get it serviced when I can buy a brand new set every 2 years, even though it may seem like a waste. I can always donate it to a friend or sell the used one for cheap.
Yep you're right tbone, i'm in the US.
