Camera alternatives for commuting (2014 version) After a few near misses by cars and two mates actually being hit I want to start using a camera for taping video footage. 

These are my requirements:


Long battery life (3h+) 
Inconspicuous (absolutely no fancy GoPro-stuff on top of my helmet)
Small &amp; lightweight
Reasonably priced (&lt; 200AUS / 150EUR / 200US)
Reasonable easy to use (with gloves, in the rain, ...)
Good enough quality / angle for footage, but no further HD++ requirements
Stylish 


I'm aware of these questions (Recommendations for inconspicuous helmet-mounted video camera, What is a good camera arrangement for city riding?) from 2010 &amp; 2012, but with camera technology advancing rapidly, most recommendations and discussions are outdated as of 2014. I thought about adding to them, but think starting from a clean slate it beneficial for everyone.



After a lot of internet research I think I boiled it down to a handlebar-based setup with one of following cameras (for people with a larger budget, this looks like an interesting comparison of mostly more expensive models):

Tachion MicroHD:


1: 2.5h - 3: 96g - 4: 200US - 6: HD/125° - 7: :(


Liquid Image Ego:


1: 2.0h - 3: 70g - 4: 200US - 6: HD/135° - 7: :/


DogCam HD2:


1: 1.5h - 3: 62g - 4: 250AUS - 6: HD/135° - 7: :)


Contour Roam2:


1: 2.5h - 3: 144g - 4: 275AUS - 6: HD/170° - 7: :)


Contour +2:


1: ???h - 3: 155g - 4: 450AUS - 6: HD/170° - 7: :)


Polaroid XS 100 (identical to cheaper Easypix xtasy?):


1: 3.0h - 3: 136g - 4: 170AUS - 6: HD/170° - 7: :/


Kaiser Baas X80 Action Cam


1: 2.5h - 3: ???g - 4: 150AUS - 6: HD/???° - 7: :/




To finally come to my questions: 

Does anyone


have experience in that problem domain / with one these models?
know about further alternatives?


Will try to update the question with further information...
A few years ago we bought a pile of the sub-$20 "mini dv" cams off ebay and they work fine as safety cams. Finding a waterproof enclosure is effectively impossible, so I used a plastic bag. At ~$10 each losing one is no the end of the world. Sample video: vimeo.com/15050277. If you're experimenting, buying a couple of those might be a worthwhile start to see how much hassle they are and how much use you get out of the camera. (I no longer bother, but then I ride to Cooks River cycleway every day and only ~5km of actual roads)

One thing that I've become more aware of/irritated by recently is the difference between 60fps and slower frame rates. For a safety cam 15fps is fine, but if you want to use the video for anything, 30fps is hard to watch. And a lot of the 1080p cameras don't even do 720p60. So if you're going to spend $200+ on an "HD" camera, try to get one that does a decent frame rate. That way when you start playing with the video you wan't get too grumpy. If you shoot at 1080p60 you can usually get software-stabilised 720p60 out of it, or you can pay a bit extra and get the stabilised Sony action cam instead.
