From what I remember of doing the manta dive off of Kona, they all charged the same (120 at the time) with the exception of one dive op, that charged 100. Once we got out it was clear that they were all the same, literally. Boats just tied up to one another, there wasn't any appreciable difference at all. I can't remember the name of that operator, but a quick search can yield the results. Good luck, that's one of the most interesting dives in the world, imho!
