I use, 21$ on amazon , some of those smaller scales you cant go over 500 grams, thats why i went with this choice.

What i do is, fill the cup half way with hot water and place it on the scale, press 0. Then add the grams, it only goes by grams. so you wont see extra 1.4 or something, once you hit that gram, you just automatically know its around the next number or in a half. Like i try to get 6 grams but want to stay under it, because i know it will be close to 6 or 5.5 grams. Reason why i got this one is because if i put a bag away, I can trow the whole bag on the scale and just write the #grams down on the bag. I am sure there is better 0.01 grams, but i don't mind the not seeing .00
Beside you can use it for other things you scale in the kitchen, like flour.
Do do the expert way and measure 0.001 , spoon take longer and when i don't have time i use the other one.
I use this spoon

I also have those old herbal salvation spoons, and i find them pretty accurate, the small side is 2 grams and bigger side is 6 grams, each time i do 3 dips flat for 2 grams, it always land on 6 grams or close to it. If you got those Lecasy spoons you can use that.
