It hasn't been serviced since I've had it (2+ yrs). Not much to service, other than replacing the O-rings. Other than that, I suspect it isn't worth it from a cost-benefit perspective. If the pix come out bad, a "new" body would likely be cheaper.
BTW, I strongly recommend shooting a test roll or two before going on a dive! Learn how various combinations of the extension tubes/guides work (throw some objects to the bottom of a pool), effective flash distances with different reflective surfaces, etc. OTD is no time to learn how to work the camera!!!
