Lol, I concede, its too rocky.
I nearly put Zeromancer, but again, too metally.
London After Midnight are up for debate though - too rocky to be darkwave or are they darkwave?
L'ame Immortelle (http://www.myspace.com/lameimmortelleband) I just discovered today. Gefallen is bloody excellent. I also found out darkwave has a subgenre called ethereal wave, which includes bands like Black Tape For Blue Girl and Claire Voyant.
EDIT: How did I forget The Birthday Massacre?
