pa diver -- Trucks are readily available for rent on the island through lots of different places. You'll certainly need one if you plan on going out on your own to some of the more remote shore dives (playa largu area etc., although playa largu itself has been washed out). Don't leave anything in the back of the truck, even in town though. Shon Mosa, next to Largu is a great place to dive and take a little picnic lunch.
pgarch6 -- They sell the DC1200 with strobe, extra battery and 2MB flash card down here at Royal Gems in Punda for about $10 less than you can get the camera and strobe alone for on Amazon. I've been using it since it came out, and an older model since before then, and they both have been worry free and take great pictures.
