After months of eyeing GoPros and Contours, I found a cheap Contour HD on Craigslist. I've been trying out different configurations and such and I've yet to find that "sweet spot" of resolution, exposure settings and mic sensitivity. My initial tests indicate that the mic sucks ass.
Yes, this is quite unfortunate because I wanna hear the roar of my engine. Instead, the sound of the wind my mic catches reduces the roar of my mighty 250 down to a faint "buzz." =/Also, unlike the GoPro, it has no 3.5mm microphone input jack for when I just want to narrate my ride... =/ Time to look into modding my Contour HD!
As a consolation,... the video quality is quite good. Currently making a bunch of test videos...
