I also got the Tanita model that displays your body fat percentage. It's actually kind of addictive and I found I was obsessing over normal fluctuations in my body weight, so I've forced myself to get on the scale only once a week (OK, sometimes twice). The body fat display is very helpful and Tanita claims it is quite accurate. You must follow their instructions for measuring it, however -- I have found that my BF is about 3-4% higher when I wake up first thing in the morning, as compared to early evening, when Tanita recommends that you measure it. The digital scale weighs in increments of .1 pound, and I think it's very accurate. The bad news: I weigh about 1.5 lb. more on the Tanita scale than I do on my old digital scale, which I'd had for over 15 years. I think it was because the old scale allowed you to manually calibrate it, and I must have been a little "creative" in adjusting it!!!
