I've got a Black Widow in my civic and I would definitely recomend them.

Its got 2 stage shock sensor, doors/bonnet/hatch, 3 point imobiliser, ultrasonic sensors for the interior (senses glass breakage/anyone trying to force one of the doors/windows), all black wiring. Its very sensitive, shits itself everytime a stiff breeze blows past or I lock a fly inside..

Was a bit pricey when it was installed (bout 2 1/2 yrs ago), bout $350 I think but well worth it.
