I bought a very cheap camera a couple of weeks back and have been pretty pleased with it.
The image quality is passable, provided you've got it solidly mounted, even at night in street lit areas it's ok. Dark country roads defeat it, though to be fair, you're not likely to find anything affordable that copes well in the dark.
It came with a good assortment of mounts for attaching to bars, helmet or dashboard and has a simple quick release for removal.
It records AVI files of 3 minutes each and they're typically 240 MB in size though this can drop to as little as 90 MB at night when it's not seeing much detail. So you'll get about 7 hours of footage on the largest micro SD it can cope with (32GB).
It stops recording when the card is full rather than overwriting oldest files and battery life is only good for about 90 minutes recording. External power isn't really an option on the bike as the connector is under the waterproof screw-on cover at the back. My commute to work is about 50 minutes so I've taken to charging it at work as well as at home, but that's easy enough as any USB power source will do.
It's possible to operate it blind as it vibrates to acknowledge button presses.
Audio is useless, nothing much aside from wind noise once you're doing more than 5mph though it'd probably be adequate in a car. There's no provision for an external mic.
Here's a still from the AVI during daytime.

And one at night in West London. It looked blacker than this during playback, but I've tweaked the gamma a little to show there is some useable detail hidden in the gloom.

Not exactly broadcast quality, but it should be good enough for insurance claim purposes, and at £40 including the SD card it's well within budget.
