Need recommendation for waterproof 60ft/18 meters camera

[Tails Margarita]

Hi,
I already have a DSLR camera so I don't really want anything too expensive but would like a small camera to take scuba diving up to 60ft/18 meters. Here's what I need it to be:
- Waterproof up to 60ft, but will take 50ft
- Compact because I'd like it to be small enough to fit in my pocket
- Shoots HD Video and pics
- A minimum of 5 megapixels (do they even make anything less anymore??)
- Not too crazy expensive because it's for personal pics not professional
Any suggestions?
