I've looked at the DIY threads on building a steady-cam mount for a bike. It's more effort than I want to undertake at this point. I'm filming bike rides in the forest for my family since none of them live in the area where I retired--I've toying with the idea of HD anyway. Price-wise, this beats the GoPro and Contour. I've got a small boat that I get out once in a blue moon; I may get inspired to get it out this summer and enjoy some of the local lakes and test the camera underwater.
