I have a Light and Motion Titan D100 housing for sale. Last August it was sent to Light and Motion for an overhaul - they replace all orings, etc, tested the electronics, tested it for depth. It was sent in for this in anticipation of my selling it; I has never had any trouble with any function. It has not been diving since. I have the receipt. This sale includes a flat port I used for a 60mm lens, and port extension for a 105mm lens. Manual focus gear, a set of new orings. Everything included fits with room to spare in a pelican case that comes with it. $1,000.
