I've been able to figure out pros and cons on other gear like BCD's and dive computers, but with regulators I can't figure out a way (on paper) to pick a regulator. The only thing I can see is the reviews on scubadiving.com that seem to always rave about the Atomic and Scuba Pro regulators. Being a newbie, is it just best to grab one of those and be done with it or are there other factors that need to be taken into consideration? Thanks.
