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
