In the market for a new reg set. Currently running the Mares Rover 2S that was my first regulator I owned when I started diving so I think anything will be an upgrade. I was initially settled on the Atomic b2 regulator but, I’ve been hearing a lot of good things about Deep6. My primary want is ease of breathing throughout the water column followed by comfort. I don’t have a dive shop closer than two hours from me so it’s not very convenient to just pop in and try some out. I know everyone has their opinion on different brands but, I appreciate the advice.
If the nearest LDS is 2 hours away you will either mail your regs to be serviced or service it yourself. With Deep 6, you have both options.
Regulators can be religious, but also a topic where people's personal agenda for retribution come out unfortunately.
The reality is, regulators from the respected companies like Apeks, ScubaPro, Atomic, Deep 6, and more, you will be happy with whichever one you choose. I highly recommend against buying based upon servicing/parts being available in diving destinations. The reason is, you want to establish a relationship with a not-so-LDS that services your gear (if you are not servicing it yourself). I've had regulator service screwed up by 3 different LDS's to me, one in which was a dealer of Apeks, but put in "close enough" parts. So just because you get your regs serviced while on vacation, you are not guaranteed to actually have correct parts. While this is the exception, not the rule, so is having an issue while on vacation. The only time I had issues with my regulators was right after service. If you have a vacation coming up and your regs are due, it is better to have them serviced after you come back.
EDIT: as you are in the US, if you go with Deep 6, you can send regs to them to service or another certified shop/technician. Or yourself.
