Thanks Pedro2 - the rental price is certainly understandable. Since I posted that question we have progressed to possibly purchasing our own digital camera and underwater housing. I am curious about what type of Cannon Powershot did you purchase for your rental units. Irm and I are thinking of going with the Canon Powershot S70 - 7.1 megapixel. (Seems like a great land camera and good enough for the underwater shots we would want.) Either way we'll be diving with you guys at Protech for two weeks this August. Can't wait! mobunny
