I bought a Grobet scale. Highly recommended. Not sure of the model # but it is a pocket version and it takes 2 AAA batteries. It goes to 100 grams and is rated to be accurate to .01 grams. Grobet supposedly is a good name in the science industry and while it was expensive at $35, I decided to do it once and do it right. I liked that it could measure in grains, carats, ounces and grams while still fitting in my pocket.
Anyway, lately my father is getting into ammunition reloading, and he recently purchased a powder scale. It is like $175 and it came with a 50g weight for calibration purposes. We put that weight on both scales and they both said it was 50.08 grams-- they matched to the 1/100th of a gram. We also weighed a couple of other items and only once were they different, and then by .01g--- and mine kind of wavered a little before settling.
Longwinded story short, if you have two scales, take a weight and put that weight on both of them. If they match exactly you can be relatively sure they are both good scales as the chance of them both being off exactly the same are pretty slim. If they do not match then you know at least one is inaccurate.
Another piece of advice prior to purchase is to think about what you want to do or might want to do in the future. If you were going to say reload, you would want something that does grains. If you are or might be into jewelry you will want carats. I chose to get one that does them all, I figured it would be more useful as I only planned to buy one that way.
Also all but the cheapest should have a tare feature, so you can put a container on the scale, zero it out, and then weigh--- effectively removing the weight of the container from the equation.
Edited to add: this is the one I have. I purchased it from Sears online, not
Amazon, but I cant find the sears listing.
