ILS approach,
Well, DTM would be the best for you as it sounds. As far as I know the DTM base is primarely Dutch/Belgian's. Which means a 2 hour drive to get home.
SXF would probably a bit more difficult or do SNBRU fly on SXF??
As a TRSS-er I have no clue if that would affect your basing.
I haven't got a lot of info about other bases, all I know is really in my previous post. You will be rated on the 319 as no new 737 typeratings are given.
Airbus bases are; LGW/STN/SXF/DTM/ORY/BSL and from 2006 EMA & BRS.
Good luck
