My apologys to everyone. Normally I do leave a source for parts.
I buy my range sensors from Acroname. I am sure there are other sources.
http://www.acroname.com/robotics/parts/c_Sensors.html
I use the GP2D02 sensor $21 that gives a digital range output 10-80cm.
The GP2D05 sensor will give a digital on/off value based upon a distance
threshold you define with its potentiometer (from 10-80Cm) $19 This means
you can set the detector to sense an object that is 30 CM away and it will
send a 1 bit output when anything reaches the 30cm mark. For the $2
differance you may want the GP2D02 sensor and you can use it for other
projects later on.
Each sensor has a basic stamp II program that acroname provides with it.
Another nice sensor for other peoples uses is the new Devontech SRF04 range
sensor available at the same location ($25). This sensor has a range of 3cm
to 3 meters, and will detect a very narrow stick within its beam pattern. I
like it for robotics and detecting narrow chair legs. I have never yet seen
the SRF04 sensor fail to detect anything. Sometimes the GPD202 will not
detect a very small tiny object. Again the chair leg as an example. For
something as large as a hand, the GPD202 would detect that fine.
Please note at 10cm (4 inches) the GP series sensors are at their lower
range of detection limit. Depending on the box size you may have an issue
here. The SRF04 will detect down to 3CM (1 and 1/4 inches) Use the
Sr_sonar_2 section of the basicstamp II program example for this SRF04 sensor.
Sincerely
Kerry

    Hi Kerry,
    Thank you very much! I did some searching for "GPR200" on
    google and other engines. Didn't have any success. And I had
    noticed that a number of other messages recently had
    recommended products or sites without providing any leads on
    how to contact...

    I'll second Kerry's recommendation. I've got the GP2D02's and the Devantech
    ultrasonic on my big robot, and they work well. Acroname's documentation is
    the tops also.

    If you want to see something really cool, I've got a Devantech unit mounted
    on a servo that will pinpoint an object as small as a pencil at about 5
    feet.
