Load Sensors

I looked at the Flexiforce load sensor by Tekscan and they look like
they will fit my needs for measuring weight (0 to 25 lbs). I was
wondering if anyone has used them and what their impression was.
Also, are there any alternatives to the Flexiforce sensor? One of my
main considerations is cost and I wouldn't want to go much higher
then the Flexiforce sensors (4 for $55).

    I don't know if this will help, but Jameco has a "Flex Sensor"
    (part number 150551, page 170 in the Sept/Oct catalog), with
    variable resistance depending upon degree of flex. In the catalog,
    they talk about it being useful for "virtual reality data gloves,
    robotic(sic), bio-metric, physics and engineering". Resistance
    varies from 10k to 30k or 40k, depending upon amount of flex and
    it's priced at $10.95 in single units, down to $8.49 in quantities
    of 100. Maybe you can use this to detect degree of travel on a
    spring-loaded plate or something? Certainly seems cheap enough to
    try one out...

    Just be sure and watch out that the sensor does not get creased or it
    will be toast. This would also apply to a repetitive action that might wear
    a "foot-print" on the sensor causing it to read improperly.
