I got a Taylor Biggest Loser scale that measures body fat and water. It's probably not all that accurate (I've read that most of these home scales aren't really capable of measuring body fat accurately) but I can see a trend downward so that is helpful to me, even if the exact percentage may not be correct. The water percentage doesn't seem to vary by more than .1 percent, so I'm not sure if that has any value at all.
The weight seems to be a lot more accurate than my old scale - that one would give me 5 different weights if I got on and off 5 different times, and they could vary by 3 or 4 lbs.
I think my new one is programmed to give the same weight as long as it's within a few ounces of the last weight, but I've tried re-setting by either weighing myself carrying a heavy object or having my 5 year old weigh himself, and then if I get on again, it gives me the same weight as before. So that seems like it's more consistent anyway- again, I'm not as concerned with absolute accuracy as I am with seeing the consistency of the trend.
hope that helps!
