I came across these guys a while ago. I really like their music. Some people think they're one of the best Synth groups ever, while others are of the opinion they wrote complete garbage. Either way, I think their sound is nice. Really geeky, too, without even trying. That kind of charm is hard to come by.

Other than that, I enjoy a lot of things that were already mentioned. Propaganda, Naked Eyes, and Yazoo being my all-time favorites.
