I would have to go with the Oceanic Delta. As other posts have said, the performance is good, but servicing it yearly is much easier. I think that how well/easy a reg can be maintained should be a consideration in your purchase. Along those same lines, if you dive locally, having a good, reputable, LDS that can help you with your equipment is imporant also. I am sure some would disagree, but in the $250-$400 reg range, most of the top brands will perform well while diving. Look at all the factors in making your decision.
