One thing which someone brought up, or at least alluded to, is to consider what unit your primary dive buddies are using. In N FL, it's a good bet someone is diving just about any unit available, and of course, support for almost all units is available as well. In other parts of the world, however, there may be more of a concentration of one or two units in any given area. The value of mentors and dive buddies on the same unit is not something to be underestimated.
