I can recommend Xiaomi Smart Scale 2 (not the body composition one, it's nonsense). It is very accurate and repeatable. So much so, that you can see your weight drop after you go to the toilet.
It is fascinating how much one's weight fluctuates during the day (or night which is even weirder if you don't eat/drink anything!)
