Good camera and mount for your head that is not a gopro?

AWBoater provided an interesting (and good) list, but I sort of have to disagree with one thing...

He said, "One has to assume that if sensor sizes are not specified, they must be at a disadvantage"... assuming you want to capture video, not stills, if the sensor is more than 3 megapixels for video doing 720 or 1080 horizontal lines of video resolution, you don't need much more in the way of more megapixels...

standard definition, 4:3 aspect ratio, video = 640 x 480 = 307,200 or almost 1/3 of a megapixel.

high definition at 720 horizontal rows = 1280 x 720 = 921,600 or almost 1 megapixel.

high definition at 1080 horizontal rows = 1920 x 1080 = 2,073,600 or a little over 2 megapixels.

In addition to horizontal line count, the amount of compression applied to the video data stream during capture has a HUGE impact (if you can, compare 1080p video at a 25 mbps to 1080p video at 7mbps using the same LARGE monitor or HDTV and fill the screen for playback - both will look fine on a small cell-phone screen...).

Megapixel count is more of a measurement of still image resolution. Assuming the manufacturer did not specify megapixel count may mean they know their equipment is not appropriate to capture high resolution still images, but we found two paragraphs ago, that does not matter for video.

Other helmet cams worth a look:

Most likely the GoPro family and Coutour will be the most "available" given the list of stores you provided.

Other than GoPro, the best POV currently is the Sony Action Cam. There are fewer mounts for the Sony version at this point, but they have just released several new mounts.

And as the model matures, more 3rd party offerings will become available.

POV camera specifications:

GoPro sensor size & lens speed:

GPH3B 12Mp BSI = 1/2.3 @ f/2.8 (uses a Sony IMX117 sensor)

GPH3S 11Mp = 1/2.5 @ f/2.8

GPH3W 5Mp = 1/2.7 @ f/2.8

GPH2 11Mp = 1/2.5 @ f/2.8

Sony Action Cam sensor size & lens:

16.8Mp BSI 1/2.3 @ f/2.8 (sensor masked off to 12mp)

Contour sensor size & lens:

Contour +2: 5Mp (sensor physical size and lens speed not specified)

Contour Roam: 5Mp (sensor physical size and lens speed not specified)

Drift HD Ghost:

11Mp (senor physical size not specified)

lens speed: f/2.8

Panasonic HX-A100D:

Sensor size: 3.3Mp BSI 1/4.1

lens speed: f/2.5

One has to assume that if sensor sizes are not specified, they must be at a disadvantage.
