What toughcam or tough digital camera do you recommend?

What is a good toughcam digital camera. A digital camera that is waterproof and shock or shatter proof or at least be able to absorb drops from certain heights? I’m looking to spend around 300$

I know that there are the Panasonic Lumix, Olympus Stylus Tough, Canon Powershot D10 & Sony Cypershot TX5.

Which model or brand should I get?

Thanks =D

I’m not looking to buy a waterproof case or housing system.
