Which Waterproof Camera?

Andy C would like to know the answer to the following question, if you have a suggestion then please post a reply:
i am about to go on holiday to Egypt where i will be doing lots of watersports as well as diving. I am also off to NZ in the new year, and I am looking to buy a waterproof camera so that i can take pictures wherever i go without having to worry about getting it wet. i already have a fairy new camera (i only got it at christmas) and have a very limited budget. so basically - what is my best option for a decent-ish waterproof camera?
