For my Garmin 800 I have a Bar-Fly forward mount on my road bike and a SRAM forward mount on my CX bike. Both hold the computer more solidly and in an easier to read position than the standard rubber band mount in either the stem or handlebar position. On my MTB, I have a Bar-Fly mount that positions the computer over the stem (more protected from being snagged by limbs etc.), but its adjustability lets me put it at an easier to read angle than resting on the stem with the standard mount. All of these are made from nylon and are very sturdy. I still use the rubber band mounts on a couple of other bikes. I have not had a band break while riding, but they do tend to move around a little, especially mounted on the handlebar.
