While I prefer Atomic (as I posted) I also own an Apeks 200 and 50 set, they really are great regulators with one exception, the purge is too easily triggered by water pressure against the front of the reg, such as when being propelled by a Diver Propulsion Vehicle, and sometimes get stuck free flowing. I have heard that the problem doesn't exist in the DS4, and has more recently been corrected (stiffened) in other models. Though I have no personal experience to share regarding this improvement.
I wish you the best though, they are excellent regulators for all around purposes. You'll not look back from your purchase. Post again after you've done few dives to let us all know what you think.
