Rando HD Mini Car DVR Video Camera Recorder 2-inch LCD w/ HDMI Cable built-in Microphone
Only had it for a few days and so far its pretty good.  Video is decent and in day light you can read license plates in cars in front.  Haven't use it in the dark to comment.  My only issue is there seems to be some audio issues with the mic when driving.  I get intermitten grabage but only when driving.  It doesn't give the same noise when outside the car and under similar use.  perhaps RF interfernce with the radio or somthing.  I dont care much for the audio so not a concern to me.
