I found one on ebay that I like. Comes with two 50 gram weights for calibration.

If you search, they have reviews of it over at Amazon. People seem to think it works well.

raizla Reviewed by raizla on . I need a scale. What do you use? :thumbsup:The reason I'm asking this in the grow section is because I want to know what you guys use to weigh your own crops. I know a lot of the people in the grow forum go for higher quality and tend not to skimp on their own stuff. Sooo..... What scale do you use? Where did you get it? How much was it? Rating: 5
