A friend of mine plays in a band called "Der Blutharsch" - they are meanwhile a kind of "Krautrock" band (and changed their name to "Der Blutharsch And The Infinite Church Of The Leading Hand"), but they where one of the bigger military industrial bands in the 90s - try to find some older stuff from them (when they were only called "Der BLutharsch"), I am pretty sure you will dig it. (hard to find tough - they let every old song be removed from youtube etc...)
You might also like Albin's (from Der Blutharsch) former project, "The Moon Lay Hidden Beneath a Cloud".
Besides that, I say, start with Laibach and go from there! you will probably sooner or later end up finding bands like Von Thronstahl, Blood Axis etc...and then you will move on to Neofolk
(that's the common "route" I saw everyone going)
In general, its pretty hard in that sector finding something that isn't total Neonazi-crap...
