Mom bought for me the Digi Cabi Electronic Dry Cabinet AD-050 for S$209 at Challenger VivoCity. The reason I decided to get a dry cabinet is because I saw some rust on my lens filter when I put my camera in my room. I only on the air-conditioner at night, so I am guessing the rust is created by the condensation of cold air. Since the camera cost about S$1.7K and it is an expensive and ongoing investment, I think it is worth it to get a dry cabinet.
