I have a Sunbeam Health o meter HDL200. It was quite inexpensive. It's digital and weighs in .5 pound increments. I find it to be consistent and accurate, weighing me about what the doctor's office does.

I always use it on tile, BTW. It doesn't work on a soft surface such as carpet.

Oh, and FYI: A recent Consumer Reports article mentioned that the ones that measure body fat are generally wildly inaccurate and/or inconsistent.
