Or buy a cheap set of electronic bathroom scales and hack it.

Bathroom scales only read to within 1lb, so 8 bits would allow a
maximum weight of 18st.

Mine has steps of 0.05kg

It doesn't matter how low the resolution step if the accuracy of
measurement doesn't match. With bathroom scales it often depends on
where you place the scales. Placed on a hard surface is very likely to
give a more accurate result than placing them on a carpet.

I doubt if something such a cheap strain gauge claiming 24 bit
resolution is any better than 12 bits accurate, and when kept at a
constant temperature.
