Scuba Diving Camera

[clowny]

I was wondering what people use to get pictures of when they dive on trips. I dont want a $1,000 camera or anything for one trip but was wondering is it better to buy a camera that can go 65+ feet deep or buy a good camera and get a waterproof case? I'm definetly looking for suggestions and any tips for Diving in Jamaica (Ocho Rios).
Also just looking for opinions should I get diving certified or just snorkal for some.
