I have identical Gordy wrist straps on the three cameras I use the most. They take a little time to soften in use, but they are neatly and strongly made, and certainly worth the price.
Before you order, it might be worth knocking up a couple of dummies and attaching them to your camera(s) for a day each, just to see which length suits you best. If I were to buy another I might take the short version rather than the mediums I have.
I also have a fourth, which is the "string" attachment type, but I would not buy another of those; I have a fear (probably unfounded) that the string will snap ...
