Mine is a bit older but was around the £180 mark. It's a Blackvue DR500GW-HD, with GPS tracking and g-sensors. Starts automatically when the ignition is switched on, records all the time and I can usually get about 2-3 days driving (approx 2 hrs each day) on the sd card. It is possible to buy a little power saver thing so it also records when the ignition is off, in response to motion or collision detected. Had it for a few years, been very pleased. Has confirmed on one occasion that a minor knock was my own fault, so drive carefully!
