So i'm looking into getting a digital scale, but i really don't know much about that kind of equipment...i looked on amazon, but there's lots, and I really don't know enough to differentiate between the different models. obviously being able to zero-out is vital, but other than that, i don't know too much...mostly what i'll be using this for is baking, so i don't need a ridiculous capacity, but obviously accuracy is important. can anyone recommend a decent scale? price is a factor; i don't want to spend much past $50 or so here.
