I have the Ultraship 35 and couldn't be happier with it. Got the recommendation in a thread posted by Pops6927 way back when. I can't possibly see where I'd need a scale to measure more than 35 lbs, but if I do, I know where to go to get a greater capacity scale.
AC/DC, dead on accurate, measures in many different formats, metric, etc.
AND, the bottom line, in comparison to other scales of equal quality, down right cheap.
