Check out the "Chesty" from GoPro. It's a chest mount and with time it has become my favorite. It minimizes vibration and you get a view over the handle bars which makes for a nice feel to the video and you don't have the camera sticking out on top of your head.

This is a video shot with it on the
Virginia Creeper Trail
I still like to use a handle bar mount from time to time and as noted above, I broke 2 of the Go Pro plastic mounts on one ride and went in search of something stronger. I ended up with the K-Edge mount after talking with the company at a bike show. I was able to take out a lot of the vibration by using a silicone bracelet, like the "Live Strong" ones to mount between the bar and the K-Edge mount. It acts as a torsional damper and stabilizes some of the vibrations. Lot's of details at
K-Edge GoPro Handlebar Mounts Review including a video of the video quality.
You'll be able to use the Sandisk Ultra but I would recommend the Sandisk Extreme with it's higher transfer rate.
