I use a Soehnle electronic scale that goes up to 11-1/2 pounds. It has a tare function, so you can set a container on it and zero it out and measure a portion. You can then tare again and add other portions to the same container if that's useful. Their scales also look really snazzy.
The Soehnle scales are about $65 at

Homeclick is a fantastic site for practically everything you want for the kitchen, dining room, and the whole house. Mostly there's no shipping charge. We got a lot of our Villeroy china at half the department store price. For that matter,we got the kitchen sink, a couple of contemporary ceiling fans, and a bunch of other stuff in the course of the condo remodel.
