I'd be interested to know how linear they are. I've personally purchased quite
a few cheap and nasty load cells over the years from the various online market
places and have been somewhat disappointed with their linearity or accuracy
over the measurement range.

$8.50 for a 1, 10, or 20kg beam loadcell and amplifier. Seems ideal for
building small solids, or cold gas thrusters, or spark torch igniters. Don't
even
have to worry about blowing it up at that price.
You still need a DAQ, but that can be an Arduino or an all-in-one or even a
recording o-scope.
