The one I use for food is a 20$ Wal-Mart. IMO that is all that is needed for food. It measures to 2g or 1/8 oz. 2 grams is almost nothing so I believe it is good enough. I have a 100$ scale that I use to make soap that measure to like .10 grams. That is pretty silly when you are talking about food though. Even with the 2 gram scale I feel a little silly when I take off a piece of meat the size of a raisin to get the portion I want. Is that 1 grams of chicken going to hurt me? I will sacrifice that little overage or underage to speed up the process. I can imagine trying to measure something like ice cream to a 1 gram accuracy.
