You may also want to check out Mayan Divers at the Mayan Princess Hotel (Mayan Divers, PADI courses, dive packages. Enjoy scuba diving on Roatan, Honduras | Home). It's just a short walk on the beach. Anja and Liber run the shop and are great folks. The dive prices at the shops are fairly similar. If you'd rather not commit to a shop beforehand, you can just walk up the beach and check out a couple of shops.
