I have the DYMO postal scale bought at Walmart (about $20). It has a 3 pound limit. I primarily weigh food bags so did not need a high weight limit. So far it is good. What I like the most is that it automatically turns off after a few minutes to save batteries. It is small and easy to haul around and I can even take it with me in the car to weigh last minute purchased items. Because it is small, it is hard to weigh big items because they slop over the edges. A postal scale will be more accurate than a kitchen scale. But it is more fragile.

I have had it a year. I previously had an expensive postal scale (from the USPS)and it quit working after I accidently put too much weight on it. I think the expensive scales break just as easily when abused as the inexpensive ones. Given my record of breaking stuff, I chose the cheap one!
