I got one of the Drift HD goggle mounts, and their Universal clip. Suits cameras that have a tripod thread on the side (i.e. JVC Adixxion), and the universal clip makes it super simple to clip the camera in and out. The goggle strap part itself can be attached to the goggle strap really easily, meaning you can easily give it to a friend or (reluctant) wife for some follow shots. Yet it doesnt come off, even in yardsale style stacks.
It wasnt all that cheap considering its just a bit of ABS, but its miles ahead of what JVC includes with their camera, and ease of use is right up there.
