I own an Oly EPL3. Given that I consider the cost of the Oly underwater housing too pricey ie. nearly double the cost of the camera itself - has anyone got any suggestions for less expensive alternatives? I'm also considering buying a decent point & shoot with dedicated housing as an alternative eg. Nikon p7100/7700 or Oly XZ-1/2. Anyone recommend P&S options? I plan to use it for shallow snorkling/swimming or in wet weather. Thanks in advance for any help.
