I'm in the market for a helmet-cam to document some of my rides. The two main companies I'm familiar with are Contour and GoPro.

Which model do you use, and what would you recommend?

I have a Contour ROAM, it seems like the GoPros have better low light performance, but I've been mostly happy with my Contour. You can see my videos at https://www.youtube.com/weshigh to see how they look. The Contours are a little bit less conspicuous on your head. It does add some extra weight which the higher up will have more change on how it feels. The GoPro seems to sit higher, but you can also get a chest mount with GoPro.

I have used both on my helmet, a GoPro 960 and a ContourGPS.
I like that the Contour is sleek on the helmet, as compared with
the GoPro that sticks out.

Here's a rather compact cylindrical POV camera. I don't really know anything about it. There was another similar one saw but can't remember the manufacturer of it.

I'm not sure if you are aware of it, but you can also 'rig' the GoPro chest mount so that it will work with a Contour camera, and it's pretty easy to do. Here is a video explaining how:

I actually think GoPro has an edge in both image quality and in the mounts being cheaper, but I like the form factor of the Contour cameras better, especially when mounted on a helmet. The GoPro cameras just sort of stick up high in the air and look a little bit odd.

See that's exactly what I'm talking about the GoPro needing
so many special mounts. If I wanted to copy the chest strap
angle, I can probably put my Contour on the shoulder strap
of a camelback/backpack with strips of an inner tube; cost $0.
Using the included goggle mount, I can attach my camera to
a wide ankle strap and wrap it around my upper forearm. The
Contour's shape make's it easy to mount in so many places.
With an old inner tube cut into thin strips, I can probably mount
my camera underneath my bottom bracket, or by the headtube,
etc.

When I had my GoPro, it came with a head strap. I placed the
head strap on my helmet like a miner's lamp. Here's a pic I saw
on the net, but the owner used the stick on mounts.
