Somehow I never got around to sending this...
I installed a Cal-Custom Hawk unit in my Volkswagen Vanagon about a year
ago.  Because of a sale plus factory rebate plus price mismarking the unit
cost $40.00 (they deducted the rebate from the price of the unit giving
a double rebate!).  Installation took 3 hours with lots of help from a 
friend that installed a unit before.  Installing the unit in the Vanagon
was complicated by the fact that the wiring harness doesn't fit a rear
engined car so a new cable had to be fabricated.  Space is also at a
premium.  Installation in a conventional car could probably have been
done in half the time.

Some features that make this unit superior to others mentioned (and why
I decided to bite the bullet and install one).

1. Speed is sensed from the ignition coil rather than from magnets on
  the drive shaft (ugh!) or mechanical connection to the speedometer cable.
  (O.K., with an automatic, this may not be so hot, but it works fine for
   a stick!)

2. Brake is sensed from connection to the brake light.  Clutch is sensed
   by a sudden engine speed change using sensor (1).

3. Throttle servo works from manifold vacuum rather than electic motor
   for much faster response.

4. Control has Set-Accel  Resume-Decell buttons like the factory units.

The unit holds the van speed to within 2 mph.  I'll never have a car
without one again. BTW I have been driving that Vanagon about 22,000 miles
a year.
