I use two scales. One for the oils and larger weights because it only measure to the gram. And a more delicate scale that measures to 0.1 gram. The smaller one is the one I use for fragrance oils and micas in order to get a more accurate measure. The larger scale is the same as the KD7000, rather than the KD8000 model linked by steffamaire above. The KD7000 has a maximum weight of 7000 grams, whereas the KD8000 has a maximum weight of 8000 grams. Only once have I gone over the 7000 grams while using my KD7000, so I feel fine not upgrading to a scale capable of handling more total weight. I prefer not to have to lift much more than 15 pounds of oils at a time anyway. To find a scale with accuracy to a single gram and hold a maximum of 20 pounds may run you a lot more money than the KD8000, so I'd suggest settling for the 17 pound maximum it provides.
