I was wondering if I should buy the Fantasea CP-3 which is a hard plastic case to protect the camera (its about $150) or the WP-500 which is a special plastic bag that holds a camera (its only $30). The Fantasea is a lot more expensive, and only fits one model, but its a lot more reliable. The WP-500 is a lot cheaper, fits lots of different models of cameras, but isn't as reliable. Does anyone have either of these models, and which one should i get? thanks!
