In Canada how much does a cheap waterproof camera cost?

I have all my canons and a Nikon but I'm going to Cuba in February and I think it would be nice to take some pictures under water! How much would a basic waterproof cost?

Choose a model here - http://www.getolympus.com/us/en/digitalcameras/tough.html and then check prices at http://www.henrys.com Henry's is a Canadian-based brick & mortar retailer who also happens to have an excellent on-line presence. I'm far south of you in Indiana, USA but I've bought from Henry's and always been pleased.
