We recently bought a new kitchen scale from Amazon
. We like it a lot for our purposes. Here is the link to it the current listing, with a lot of reviews. Price is now at $25, free shipping.
It does measure up to 11 pounds, and to fractions of an ounce. It has the ability to zero the container and then give only the weight of the added ingredients.
Not good for weighing large packages though -- they tend to cover the dial so that you cannot read it.
