I know the Zeagle got great reviews in Rodales... And we sell a ton of the Zeagles, and the Atomics... And side by side - I personally think the Atomic smokes the zeagles. I love Zeagle BC's - but in the reg department - I really feel the Atomic is worth the extra money. The ScubaPro 600 or 650 is also great... but we don't sell as many of those since ScubaPro does not allow any shipping.
As far as service on them... That piston design is nice and generic - and even if there is not an Atomic Dealer handy - you can normally find an o ring and a seat to match up. For example, you can toss in Tusa 400 first stage IP spacers in - or ScubaPro, etc. Although a lot of the things on the reg are innovative - they accomplished it while keeping it simple and standardized.
