I know absolutely nothing about underwater photography but I am looking for new challenges with my diving. I own a 20D for which I no longer use much top-side. Would this model be considered too old from which to use as the foundation of building my first system? If not, would it be advised to purchase used housing in lieu of new? Lastly, is there a book out for UW photography that is generally considered to be the best? Thanks! Scott
