If you're happy to shop online then take a look at amazon.co.uk
Popular ones are Salter Nutri-Weigh scales which have a built in nutritional menu or Salter Platform Kitchen scales which are straightforward electronic weighing scales (the ones I use).
A good set of digital scales with ' tare' function and a good carb counter book is all you need. Most of the nutri -scales are limited in what you can add carb - wise.
Most of them have codes that you input, I like to keep it simple !
