I have no other key. The key in Die Fliegen der Palaearktischen Region is hopelessly out-dated and, unfortunately, the British key I have (yes, Stuart's ols concept key) does not cover all Dutch species. I would not mind having a more comprehensive and recent key either. ;)
I am currently using two keys for North European material:
1. W. Hackman 1956: The Scatophagidae of Eastern Fennoscandia (Societas pro Fauna et Flora Fennica: Fauna Fennica II).
Hackman's paper is already quite old, and somewhat oudated, and the genitalia figures are terrible, but they keys are OK.
2.Sifner, F. 2003: The family Scathophagidae (Diptera) of the Czech and Slovak Rebublics (with notes on selected Palaearctic taxa). Acta Musei Nationalis Pragae, Series B, Natural History, 59(1-2):1-90.
A new summary of one of the best-known Central European faunas with keys and ultra-condensed descriptions. The keys include many species not yet found in former Czechoslovakia.
I find neither really satisfactory - especially the keys to genera are often difficult to follow without previous experience. Sifner's keys suffer from many small errors and some steps make sense only is you are familiar with the group. My 'favourite' is this gem in the key to genera:
32 Fore tibiae interiorly with one to two rows of very short bristles or without them -> 33
- Fore tibiae with or without anterodorsal row of distinct bristles -> 35
