Semi-similar to Prodigy or the Chemical Brothers, in order of amount on my Empeg:

The Crystal Method (you will like this, get Vegas first)
Orbital (less hard than the Chemical Brothers, but great)
Underworld (kind of like Orbital, get the later stuff.. early stuff is 80's synth, kinda)
Apollo 440 (I also like their James remix of Sit Down)
Goldfrapp (beautiful female voice as lead, she's pretty much the band)
Royksopp (almost relaxing techno)
Fluke (harder, listen to Atom Bomb on the Saint soundtrack to see what they are like)
The Propellerheads (the best James Bond remix ever: On Her Majesty's Secret Service)
Boards Of Canada (between Orbital and the Crystal Method, kinda)
Daft Punk (synth-techno)
