Kitchen scale to measure small quantities (100g max) (Harborne B17)

Hi, I already have a kitchen scale that measures up to 10 kg, but it's difficult to use when the quantities are less than 200g (for example protein powder).

Analogue scale preferred but battery-operated would do too.

 I will collect from Harborne, Weoley Castle, Selly Oak, Shenley Fields or Northfield. Thanks.
