Car mountable camera question

i would still like to check out one of these and see how good it is.
but its a pricy. shockproof unit.

I already have one of these but the vid quality is to be expected for such a small camera. its just a sony 1/4ccd camera that connects to a HDD/battery pack. the low light recording was suprisingly good. but the “bullet” itself lacks a 1/4" standard tripod thread. so it has to be Taped/strapped to wherever its mounted. I have a tripod mount on the rear deck of my car already.
