About 6 years ago I bought the Canon AKT-DC1 kit for my Canon D10. The underwater straps were fantastic. It had shoulder and neck straps that allowed you to swim rigorously with the camera in a way that wrist straps don't allow you to do without banging the camera around.
I've ordered the Olympus TG-3 since my Canon D10 is getting a bit old and I'm not sure how much longer the seals will last. But I can't find a neck strap for the TG-3. Are there not any good generic neck straps for underwater cameras? I'm an avid snorkeler so floating straps aren't interesting to me since I tend to dive quite a bit for good photos.
