I use a small Nikon 3300, and it takes pictures of the quality I like.

You have to consider the weight and volume of an SLR in packing both on the bike and for the air travel.

I took a Sony video camera with me on our round-the-world trip, but the vast majority of the footage is still on there, untouched. I did download and edit a segment to do with our cycling in Japan. But the thing is, you have to plan, script and edit to get a really effective and viewable production, otherwise it's going to be just like those old movies your grandparents would set up on family night. So unless you have a story to tell right from the start, and are prepared to work to get the commentary and overdubbing right (remember that technically, most music requires royalties to be paid), they'll be memories for you and mates to keep.

Having said that, I have just bought a Garmin Virb (the basic model) because it was cheap, and I wanted to see what all this was about. It's sleek, and discreet, which the Go-Pro isn't. It has a small screen and variable wide angle options and run time on the batteries isn't too bad. But would I take it on an extended tour? Probably not. It's just something else that I would have to worry about losing or getting nicked.
