I like this one. It's pretty complete, but I hate using it because the user interface is so old-fashioned. It's not that the interface doesn't work well, it's just a bit hard to use with the keyboard and rather hard to find where the functions are. It also contains a decent list of abbreviations. The dictionary section is reasonably complete and the number of errors relatively low (but I have seen one or two). The definitions range from the mundane (Schraube = screw) to the highly technical.
