My thoughts: If you travel a lot and will not be diving cold water below 45 to 50 degrees I would go with the SP MK25 and a S600 or the new 250 second stage. I have two and they are super easy breathers - and are adjustable for prevent free flows in current (or to tune down your octo so it does not free flow when you giant stride etc). This reg will work perfectly as deep as you ever need to breath. It can be serviced easily all over the world. The warranty is outstanding with free parts for life as long as you have it serviced yearly. My LDS has even replaced tge major metal fitting that seals against the 'O' ring on a standard yoke tank valve - after 300+ dives.
Now if you travel less (or plan to service the reg yourself, although the service method is same as APEKS FSR) or plan to dive in cold water regularly, I would look at the Salvo SR3 first stage and their SRX second stage. I just picked a couple of these up for my Doubles rig and they seem to work perfectly. You can not beat their value and Salvo sells the service parts freely.
I hope this helps. Just for the record I also have a couple of Mares Abyss regs and they breath fine, but I do like to be able to at least "tune" my Octo. The Abyss 2nd stage can free flow easily when you first jump in and it is not in your mouth.
