Also, don't assume that a more expensive reg is really any better. For example, the Atomic line is pretty much identical mechanically from top to bottom of the line, with only some small materials differences in key components for various reasons Titanium in some, but not others due to Oxygen compatibility, etc).
Also look and see if the Extras you get by going up the line will be useful in the long run. E.g. swivels that may go away or become unnecessary if you go to a long-hose configuration.
And +1 on choosing something that some local, who you trust, can service. Also consider service policies and intervals. We went with the Atomics partially because of the two-year/300 dive service interval -- it works well with the moderate amount of diving that we intend to do (enough to be out of the "sitting around, should check 'em" range, but not nearly enough to the "wear something out" range.
