You probably already know about them but Fischerspooner is in the same vein, there is another group called Adult, most of their albums aren't that great, but their first, Resuscitation is quite good.
Also the Playgroup DJ Kicks is a great mix of synth-y tracks but I wouldn't really recommend his own albums.
Ladytron is another great artist to check out if you haven't yet, and of course stuff like Fad Gadget, Gary Numan and early Human League (pre-Dare) if you want to hear the O.G. stuff.
