+1. I second that. You shouldn't have given it away with the car bung, aparade.
One more thing you should note is that most of the chinese cameras advertised on ebay which have Full HD, 1080p, HDMI etc mentioned provide decent quality, but aren't actually HD. For a camera to be HD, it should have at least 720 or 1080 horizontal resolution, so make sure you look at the actual resolution if you want a high quality camera.
The camera you have linked has a recording resolution of 1280x480 which is standard definition (SD) video.
Say for example you buy a low end and a high end camera which can record in 1080p HD, both will capture the video in HD, but what matters is the compression applied by the camera on the recorded video. The low end camera will have a higher compression, hence more discarded video data which results in a lower quality video, whereas the high end camera will have a lower compression, hence less discarded video data which results in a higher quality video.
So ultimately even though the resolution is the same for both the low end and the high end camera, you don't get the same video quality.
If you're on a budget, a basic chinese SD camera is fine, but if you want full HD quality, try to go for a slightly higher end camera with a recognized brand. I saw several Transcend dashcams advertised on sites like *ow.lk and m*store.lk for around 20k.
