I too have the DAN insurance.
Many people recommended DEPP, but after reading their policy, there was a clear reason for digital shooters NOT to go w/ DEPP - they do direct replacements only.
Therefore, if you have an "out of date" digital setup and you flood it, they send you a "new" out of date camera. Imagine if you flooded your Olympus 3040 setup. You'd want to upgrade to a newer camera. Instead, DEPP would send you a new 3040.
DAN sends you a check for the declared value of your losses. So if you feel it's time to upgrade after a flood, you can do so. That is a BIG plus in digital, IMO.
