Tanita has some that are 'FDA registered', which may only matter if you're trying to get your health insurance to pay for it. Withings seems to make some decent ones as well - including one that can estimate pulse velocity (a proxy for arterial flexibility). Look for ones that use multiple frequencies as that sidesteps at least one of the issues with BIA. Also look for 'multi-segmental' (separate readings for legs, torso, arms). Those have hand grips as well as foot contacts.
Lutz is right that they're nowhere near as accurate as a DEXA scan, particularly across individuals, but I think they can be useful to see changes in the same individual from one day to the next. Unfortunately with BIA, potential accuracy goes down as fat percentage goes up.
