I am buying a mount I tried out at Thunderhill Hill this past Friday. It is a large suction cup and it holds very steady and can accept any type of video camera. It is $120 but well worth the cost. If you are interested, PM me and I can show you some of my videos and give you the guy's contact information who sells them.
If you want a camera with great image stability and quasi HD, get the Sony HR11 and get a Flash card. You need to record onto the Flash memory to avoid having the included hard drive turn itself off due to vibration.
