I use an olympus tough camera. They are about $250/300 but they are good for just about anything except a deep dive, more than 20 feet.
I have a galaxy s 3 right now and I might be upgrading in a bit so probably not that. I was looking to use it in my tank and I was asking for it for Christmas. Considering I am 15 $1000 is probably not going to happen lol. I get your point though thank you. I'm thinking maybe around $100 if possible so that way I can get a good amount of coral lol.
