First link isn't working for me, looks like camerahacker.com is down this morning.

The latter is just a regular tripod ball head screwed into what is probably a grounding clamp with a u-bolt going through that. It's a hack. It is something I'd assemble myself, but not something I'd expect to go buy as a finished product.

Vibration is the killer. I use an Oregon Scientific camera, which was $80 and I'm not terribly worried about it; it has no moving parts including the lens. I'd kind of like to mount my Canon, which gets way better picture quality, but it had a lens with actual moving parts, and I think if I mounted it hard to my handlebar, I'd destroy the camera pretty quickly. I might work out some kind of parallelogram mount, but it would be for fair weather only since I don't really want to ride with a full-sized weather box on my bars.

If you have a Kodak, I'd make sure to use a shock mount. My experience with them has been very bad; they seem to break for any reason at all.
