AWS Gemini-20 below $100
Or a precision one for $$$
All the other sub-$100 ones are mostly junk, with a few decent ones. But just get the Gemini-20
Mine was a $30 gold scale from Amazon. Probably not accurate but provably consistent which is what I needed. I'd compare each dose and used a calibration weight to verify.
Like buying a five gallon boiling flask, one assumes this will get one put on a list in the US.
