I don't have the latest and greatest, probably because the first couple I bought were anything but that! There are so many variables that can affect the scale readings as far as bodyfat %, I don't think any of them are worth the price (or the frustration when the numbers stink).
I would recommend saving the money you would spend on a fancy scale and using it towards: 1) a plain old scale (to track trends), 2) tape measure, 3) cost of having your bf tested at a gym or health club with calipers.
