OK, I am going digital

[jmohns]

OK I am going to give in to the new technology.........I am going to buy a digital camera. I need help as to what will get me the most bang for my buck. I have looked at the sealife brands and have been pleased but I am wondering if I get a normal camera from the store if it will work under water in a case designed for it or if it will have focus and color issues. I dive primarily freshwater and vis isn't always the best. I know very little about this and would enjoy any advise anyone has to offer.
