Consider using a private, PADI certified dive instructor -- Ross James divingandsnorkelling@gmail.com I just returned from an exceptional dive trip, went by myself, to Phuket (Coral Island, Shark Point, Anemone Reef, Three Trees, Similan Islands, Richlieu Rock - Surin Islands) 2/24 - 3/6/08. I contacted Ross (I know his father in Oregon) and he made all the arrangements, knew all the dive sites, was my own personal dive instructor/guide, picked me up at the airport, etc., was cheaper than any other arrangements I could make and more personal attention. It was a great way to go. At least consider emailing him and it might be a better arrangement for you than trying to find a good dive company. I'm sure they exist, but the way I did it was in my mind more reliable. Bonnie
