Subject: force gauge/transducer

Anyone know of a simple... quick... force gauge or force transducer...
20 - 30 grams max with a resolution of .1 gram. that I could make or buy?
I'm working on a wind tunnel for my grandson's science fair project and
we need a way to measure the lift and drag.
I can measure lift with a beam balance scale... but the drag is in a
horizontal direction and because the force is so low, I hate using a
pulley arrangement to change the direction from horizontal to vertical.
Oh... and did I say cheap?
I'd settle for a spring gauge if I could find a source... that's
accurate at this low a force.
Thanks.... Jan in Gilroy
