We have a very cheap one that always needs to be re-calibrated every single time you step on it, so I was wondering what a (cheap/decently priced) one would be, if anyone has any suggestions. Should I go digital, or do they have the same problem? I'm tired of using scales elsewhere and finding it says I'm 20lbs heavier or 10lbs lighter. It makes me feel I have no accurate idea of what I actually weigh. Thanks.
