I bought the 0.01g scale initially for wine making where my 0.1g scale just wasn't cutting it. For brewing, I use it for weighting out hops, spices and k-meta to get rid of chlorine and chloramine. I use the 0.1g scale for measuring priming sugar. I really can't imagine brewing without them.
My .1g scale is fine for measuring hops even in very small quantities for 1 gallon batches, but i did spring for a better grade than the ones intended for more recreational uses. Reputable manufacturers will specify the minimum weight it should be able to measure accurately.
A few weeks ago i went looking for a vendor to sell me some disodium EDTA for deep cleaning purposes (used carboys that MAY have some mercury salts clinging to the glass) and discovered that purebulk also sells pure synthetic caffeine, and it's CHEAP.
And then when i held 100g of pure pharmaceutical grade caffeine in my hands and realized that it's enough to kill me a bunch of times over, I ordered a .001g scale.
They also sell precipitated calcium carbonate (chalk), citric acid (but only 1kg at a time!), and some other straight up chemicals, minerals, and extracts that may be handy for brewers and wine makers.
