Need help designing pressure/load sensor

Need help designing pressure/load sensor

Need help designing pressure/load sensor

(OP)
I want to design a foot pressure monitor.  The goal is to design a surface where if you place your foot and apply a certain load, the device(s) will be able to monitor the amount of load being applied from different parts of the foot.  I have tried looking into strain gauges and load cells (particularly those in the Wii Fit Balance Board) however I need some help being pointed into the right direction on what components to use for designing and pulling data.  What would be the cheapest way to accomplish this?

RE: Need help designing pressure/load sensor

(OP)
I've looked into commercial/industrial products, but they are too expensive.  I am looking to have this done with a $100-200 budget.  I was thinking perhaps several load/strain circuits would work.

RE: Need help designing pressure/load sensor

...the Flexiforce sensor that is.
