For scales I'd recommend either buying the cheap stuff (<15) or get something actually decent (but will cost more). Have bought the former twice (in multiple guises) and had both fail on me after a year and a bit (hot liquid, spills, etc - not unexpected); now have a Timemore and hopefully it'll go for longer (but only had it for a couple of months so time will tell). The increased sensitivity is a massive plus though, in addition to my hoped-for longevity.
I've found basic 'jewellery scales' from Amazon or similar to work perfectly fine, mainly use one of these now: https://rhinocoffeegear.com/rhino-coffee-gear-brewing-scale-3kg.html
Think it cost around £30 or so
