I have a full Sea & Sea Motor Marine 2- EX system for sale. It includes the camera (in fantastic condition), a Sea & Sea YS 50 strobe, strobe arm and connectors, a VF15 view-finder, a 16mm lens, and a macro lens. For $1500, I will throw in the pelican case it has been in. Although it has been around the world, it has been used very infrequently and kept in great condition.
I wish I had seen this before I purchased a new camera. I have a Rebel 300D but was told you couldn't find a housing for a decent price.
