Hi there Primaris,
Had a look at your link to the ebay camera and it would work fine i noted that the deal included a mic which would be an inline powered mic which again would be perfect for this application. Just a note the Neuros leads are rca so 'might' need an addaptor for the lead form the camera. cost you a dollar from any Tandy store or alike. Also the neuros records in stereo so get a 2-1 rca connector to get the audio on both channels again easy to get and cheap.
The recorder comes with a remote with a one touch record when the unit is live so no need for a screen in car just be sure of the position of camera. Don't connect it upside down like I have in the past.
Power will have to come for a reguated source again shop around for a 12vt to 5vlt pos centre REGULATED source especially it you use the car bty as it can spike with rev changes etc.
The device is marketed as an in home unit so extreme sports will put any claims against defect at risk but I have done lots with mine without failure so live a little

Patch
PS there is a little red light on the recorder which comes on when its recording - very handy
