Waterproof Case

Since we have been spending a lot of time in the water I was looking for a way to bring my DSLR Canon 40D with me because there are a lot of chances for good shots. I had something simple in mind, a case that would simply protect it from a little splash here and there. I either got bags which seemed useless or contraptions like these from Hugyfot and Ikelite which cost between $1400 and $5000, about the price of two to six cameras without the lenses. How insane is that, I wouldn’t mind getting one but that is a little too much for me, maybe for those who dive but their doesn’t seem to be a simple clean solution for what I had in mind.
