Recommend a bathroom scale

I’d prefer to buy online and don’t want to spend a fortune - maybe $30 - $50 or so, but how do you assure yourself that a scale is accurate now, and will be accurate for a few years?

Any suggestions are welcome.

I have a Tanita scale, and it seems very accurate. Weighing myself multiple times in a row always results in the same, uh, results.

Thanks for responding, DeadlyAccurate.

Which model, please? - if you don’t mind my asking. I’m sitting at…

…and they have a bunch of 'em.

The body fat analysis part is worthless, though, as my husband found out when he had the gym measure his body fat.
