I know your question was directed to photo64.. if he and you don't mind I will give you my two cents..
It totally depends on your budget.
One thing to keep in mind with this hobby and the photos you see, getting any camera of high quality will not automatically make you a skilled photographer. If your wanting a point and shoot with a perfect picture - It will never happen. It might (rare), but it will take some learning, patience and knowledge to get "excellent" pictures. Then again, you may never get the pictures you deep down want.
I just want to clear that up. Alot of people get sucked in after seeing great pictures, run out and buy a cam and then get really frustrated when they don't get like results or better. Doesn't work that way.
I myself have a $1700.00 dollar camera. Canon EOS 20D. The pictures I post are "OK" as is. I have yet to fully learn the system and get the best results I can from it. Once I achieve that, then I will be on my way to happyness. There are also many lenses for my camera, one of which I will be purchasing soon (macro lens) and that will aide me in getting even closer, tighter shots of my subjects.
Anyways, long story short - its all in how much you can spend, how much time you are willing to take to learn your camera and what you want to achieve with it. If your just "taking pics" and nothing more, no need to spend lots of money. Get a mid level or better. If you are going to be using your camera beyond reef photos - consider getting a better camera.
Any questions after reading this, I will be happy to help.
Again, no offense to you or who you were origionally asking.
