Has anybody built a low-cost strain gage amplifier?  I'm not too
concerned with temperature compensation and will most likley be using
a full bridge configuration.

I'm attempting to build a force measurment system using an aluminium
bending-beam load cell.  The beam must have about .25 to .5 inch
deflection for a full scale measurement and some measure of the
torsional forces would be nice.

I am building both the beam and the amplification circuits (two
channels) so any help would be appreciated.
