Thinking about bike cams again! We have a voucher for £100 off a gopro which is tempting as it puts the gopro hero 3 black edition at £260 which includes waterproof housing and remote (or the silver edition at 180 but that doesn't include the remote which is £80 so worth getting the black if just for the remote). For the drift alternative it would be £295 which includes a remote but not waterproof housing (although thats not too important as I've not been diving in years and its waterproof without to 3m anyway). I'm put off the gopro as it couldn't really be helmet mounted. I have stick on lugs for my lid that I use on charity rides and the drag from them is bad enough at motorway speeds. I like that it can be chest mounted, although I am not sure how good a view that would provide on a faired bike with a smoked double bubble screen! The drift can be shoulder mounted with a similar harness. The gopro does hd slow motion which I think would be really cool. Also claims low light performance, not sure how that compares with the drift. :/
