Just got my Palmscale 6.0 and it is even better than I expected. Amazing the variance in the weight of chips. This is not a scale to end all scales. Being a pocket scale it is not much bigger than a Palm Pilot but it will weigh up to 20 chips in .1 g as well as small envelopes up to 8.8 oz. and the best part is you can take it anywhere. Similar models range from $20-$100.
