I was using a little Olympus sp-350 in a housing with some pretty decent results but flooded last trip so a replacement is needed

Ideally i would buy a camera and a housing again as it means i can also use it for holiday snaps etc.
I have been having a look at these http://www.camerasunderwater.co.uk/d_st ... e_g--.html
but as said previosly dont have a clue when it comes to cameras

We are taking the little one away with us this trip so will probably pick her up one of those waterproof / shockproof basically break proof cameras just for snorkelling
Ive seen the olympus one but thats about it are there any others?
