I have that optical cable Adam linked. It is a neat looking little thing, plus it's very flexible and easy to work with. Plus plus, I think it would be hard to break the glass fibre with the braiding around it. No issues with performance, as you would expect.
One thing I have found with Monoprice cable is that they can be a bit inflexible, especially the component RCA cable I'm using. Every time I plug it in or move the equipment, I think I'm going to break the RCA socket off the receiver. The HDMI cables are not near that rigid. They are easy to work with.
