How do you know if a personal/home scale is effective?

Are digital scales always better than the ones with dials?
Why are some more expensive than others? Do the more expensive ones garantee better accuracy? And if they do, how do they do it?

And yes, I did join the site just for this thread. lol. :p

Come on ladies, help me out.

not a lady, but as far as digital scales go they can get really sophisticated. some give bodyfat%, total body water, fat free mass, basal metabolic weight. and probably a bunch of other stuff.

look at tanita scales if you're searching for one.
