I used an Ohaus 10-10 for many years. It needed lots of attention to the blades and anvil. I bought a $40 Frankfort Arsenal electronic and it never would settle down. I had a Lyman Accuscale that was replaced by Lyman following the troubles I had with it. I gave it to someone I didn't like. I am currently pleased with the Sartorius Acculab. It reads to .02 grains or .001 grams. Sinclair has it Powder Scales | Powder Handling at Sinclair Inc
I have bought a used scientific scale that also is reliable and repeatable to .0001 gram. I use it to sort primers and bullets.
Buy the most expensive scale you can and you will spend less on scales. Plus you will load better ammunition. Spend more on your scale than on your press.
