Dee, I agree, one policy isn't for everyone.
Here's the way I'm looking at it. Even with a PT housing, it does still make sense for me. About $700 cost of the camera/housing. If my camera is flooded 18 months from now, for only $250 I have my choice of entirely new system.
With DEPP, as I understand it, I'd be covered for the $500 on camera (less $50 deductible) and the best I could do is a replacement of the camera. If that's not available (new or refurbished), I pay the difference for a new camera, plus I might need a new housing. Total out of pocket in that scenario is the $200 for the housing, $50 for the deductible and whatever difference for the new model. Not to mention DEPP is slightly more expensive to begin with due to the way they calculate the policies.
The two come out pretty darn even. In that case, I'd rather have the cash and control over what I purchase to replace the system. Since digital technology is changing so rapidly the liklihood of a camera to fit my current housing in 18 months is questionable (though I could purchase a used or refurbished myself - my choice). Cash gives me more flexibility.
At least now we really know how to evaluate and compare these two policies to best fit our own needs. Information is power!
