I have a Salter 'diet scale' aka Colorado ( not sure if that name has anything to do with recreational use of herb there , but I don't think so )...
This is a small scale, measures to 100th of a gram and up to 500 grams. I was initially very happy with this scale, but over time, something happened and it doesn't like completely shut down and burns through batteries even when not powered on, so I'm less happy with it now. I have to stick something in it to prevent one of the batteries from making contact, in order to avoid it draining batteries when not in use.
I originally bought it, because I was able to buy it locally , I ended up paying like $25 for it, even when I knew you could buy similar scales for half that price online.
Meanwhile, for me, the ability to weight to 100th of a gram resolution is important. My main use for that ability is in measuring yeast for single pizza sized dough balls, and to be able to achieve the kind of accuracy in measuring this small amount of yeast... It is also handy for measuring cure in small amounts, but yeast measurement is really the main reason I want and/or need this resolution.
When it comes time to replace what I have now, I'll be looking for something different, but highly doubt I'd ever spend more then $20 on one. I'd love to have a scale that could measure 100th of a gram on up to a Kilo, but as near as I can tell, they don't exist in anything reasonably priced, and at the prices I have seen for scales that might do it, I'm more than happy to buy one small scale, and one lager one ( with less resolution )
