My sour-faced two pennies worth:
1) "The undisputed best."
2) Not really looking for an opinion but rather confirmation.
3) Tossing off big numbers like it's no big deal.
4) Only using it for warm water rec diving.
Call me cynical, and don't take this the wrong way, but it sounds uncomfortably like you're more interested in showing off your reg and its undisputed superiority, than in using it. If so, you really should consider collecting Leica cameras instead. They
are the undisputed best. And universally prestigious, even among lay people. And ridiculously overpriced to boot.
Seriously, you'd be better off if you were thinking in terms of the
right regulator for you and your diving habits rather than the
undisputed best. The right reg may not be the ultimo top-of-the-line...so why do you feel you need the ultimo top-of-the-line? For your diving it sounds like just slightly overkill to me.
I'll second what the others have said about local service being a key consideration--I'm not aware of any Atomic dealers here in central Ohio, fex, so even if I did have wads of disposable cash I wouldn't buy an Atomic. I'd personally lust for a mid-range Scubapro, a G250/MK16 or something. You'll probably never have to worry about service with Scubapro. I hear they're great breathers too.
I will say that from what I hear Atomics are definitely very good regs, but on par with other higher end models. Obviously not
undisputed, judging from this thread. Better keep researching.
