From an old Dexa Thread I have the Tanita BF680W that Nate was comparing to Dexa, unfortunately no longer available and not sure what current models would be similar, but the Tanitas are always decently priced so possibly also worth looking into.
Looks like I bought it about year after my last real BF% test so I never had any direct comparison like some of the TR staff did but having had a bunch of tests previously did always feel it was decent for tracking.
