Eeeek... I have been away from the forum and not had a chance to check into this thread! Thanks for the tips girls
I have decided to go with Blue XTS diving as they have so many good reviews on scuba forums.
I just got the Lonely Planet Diving and Snorkelling Cozumel in the mail yesterday and have read it cover to cover... wow am I excited now!
Topical fishies here I come!
