DYMO M25 is excellent. I've been using the DYMO M25 for the better part of a year. I needed a scale that would weigh packages up to around 25 lbs. It does that very well, but is sensitive enough to weigh letters. Connected to a computer (I use a Mac) via USB and used with software such as InstaRate you can determine postage and even buy and print it, if you choose. Tech Support is excellent: in addition to phone and email, DYMO offers Chat, which I used very satisfactorily to find out about postage software, which is not mentioned in the User Guide. In sum, the DYMO M25 is a well thought out and designed postal scale, that is compact and easily stored and therefore accessible, that does what it is supposed to do very well.
