There’s something to be said about analog scales. You don’t need to worry about batteries or power failures. All you need is Newton’s Laws to keep working, and your scale will tell you the right weight. There’s no school like the old school.
Taylor is one of the best known name in scales, and their mechanical kitchen scale is a close match the the Animal Crossing one. I have this model, and not only does it save me from having to buy new batteries every other month, it's actually much more accurate than the digital ones.
