I rescued an old Ohaus triple beam chemistry lab balance and a set of test weights from a dumpster at one of the universities at which I worked. It reads directly to 0.1 gram and has a capacity of 2 kg. It is highly accurate but has more precision than necessary. One gram is 1/28.35 oz or 0.035 oz; that is more precision than I really use and the tenths grams readings are way overkill. It can be slow to use but, hey, the price was right. I did have to wash a lot of ketchup and mustard off of it though.
