I would certainly think between Cayman Brac, Bonaire, and Maui, we would have it covered. I took my camera to Cozumel this past September and used it with only the built-in flash and I got a few good shots but after that trip I knew I needed a real flash if I wanted to take some pictures that would be worth framing. I think the AF35 is a good choice for a flash. I looked at several and for what I want to do as far as underwater photography goes, the AF35 seemed to fit the bill.
But we'll know soon enough won't we. By the way, I'll also be headed to Cayman Brac in May.
