There is no right or wrong answer here. Remember, all gear on a diver must be of equal capability. A super-premium regulator is the choice if everything else, including training and skill, can go to the depths where these regs excel. It takes big bucks gear, and training to go down to 200 feet. By the time a diver is ready to go there, they will be experienced enough to know exactly what they want.
I consult other divers around Central Florida before buying gear. If a brand is popular here, service is readily available, too. Some manufacturers are not represented equally strong in all parts of the US. The best choice for a guy in one state may not be the best elsewhere. If you were here, I would advise Oceanic. It is sold by large and small retailers, priced right, and there are a variety of models and features to available. They are highly rated in comparison tests. If the time ever comes for a reg to go really deep, you can get a good money selling a used one.
