Goodness graceous rob1, you will only pay 80 dollars for a scale, what do you expect?

I agree however, 10 dollars of extra filtering and capactance is all it would take I believe. I just don't get it sometimes. Maybe cause I don't care about Bill of material cost where I work, but a little extra effort in designing something can go a long way. I doubt however that the cost margins are that great on those little scales. So to be competitive, I would say they save every resistor they can.
