Thats what I've got- a Contour 720, (not the 1080). I've got a 16 gig micro card and a spare battery, so I can pretty much record 4 or 5 hours at a time. 4 days riding- 30 minutes of really cool stuff packed into 20 hours of video...

Now I get to spend 20 hours watching boring climbs to find each of those really cool 15 second clips. I gain 10 pounds just thinking about doing it!!!
