Just been diving with Rainbow Divers in Nha trang (Viet Nam), they are very professional and the price is pretty good for 2 dives ($60 pp) That includes all equipment, all fees and refreshments.
We did 1 dive at Debby Beach and 1 at Moray Beach. We have no photos from the dives as our camera doesn't have a housing, but we took some whilst snorkeling in between. There not going to win any awards. We saw Moray eels, Puffer fish, Barracudas, Cuttlefish Parrot fish, Angel fish, Wrasse and some of the other usual suspects. It took less than an hour to reach the dive site from the centre.
