The cost of dive excursions offered by the ships often appear excessively high until you factor in dive equipment, except wetsuit, and any transportation to/from the dive op is usually included in the cost of the dives. Sometimes dive excursions are offered in two options, one with equipment and one without. I always travel with my own gear, and the last time I was in Roatan, it was actually cheaper to dive with the ship's op, AKR (one of my favorites ), than one of my other favorite ops (Barefoot Divers), after including transportation costs.
