Beurer. Bought it this past weekend from Bed Bath and Beyond as another user suggested it for me. Its memory holds up to 10 profiles. Input your weight, height, sex, activity level etc, step on the scale, and it clocks your weight. Then every week when you step back on, it will tell you your weight and the increment in which you lost, or gained.
It also calculates your body fat, muscle, and water %.
I believe it was $30, and BBB always has coupons for 20% off, so I saved a few bucks. They also are good when it comes to returns if anything were to malfunction.
So far, It's a great purchase.
