Travel much? If so, the Balanzza digital luggage scale might be a good investment. The unit costs only $22… which is a bargain considering airlines are charging between $50-$150 for overweight bags. The unit is made of ABS plastic and steel and can weight up to 100lbs. Or you could weigh your luggage the way I do… hop on the scale with your luggage…then hop on without your luggage and subtract the difference. I guess I am a cheapskate.
