Hey Elizabeth,

I had a ~$20 digital scale that had a precision of 0.01g and a maximum capacity of 100g. It worked great for a limited time and then died. I was hesitant to buy another one of these, or something similar, as I figured I may be throwing good money after bad.

I settled on an old and familiar favorite.

The Ohaus Cent-o-gram quad beam balance

311g capacity with 0.01g precision.
