Cant tell if you are in the states or not, but if you are you can buy a great little gram scale that reads in tenths of a gram a place called HarborFreight.com on sale they are $10 or not they are about $15.

For refilling, a scale that weighs to 0.01 g is more versatile unless you need to weigh big stuff. Amazon.com sells lots of them for about that price. Look for 100 g or 200 g capacity.
