Anthony Rother has an excellent live-act performance: he plays keyboards, does vocals and his electro is danceable even to people who aren't into this kind of music... Check out also Alexander Kowalski - I personally don't know what equipment he uses for his live-acts nor am I informed of how he plays it (live playing? sequenced parts? improvisation?), but his music and performance are definetly worth hearing / seeing.

With the aid of software like Ableton Live, live acts are more accessible to performers on a low budget, but it brings up the debate over whether using loops and sequenced parts can be described as a "live-act"... But nevermind that - if you want to start playing around with live-acts, Live is a good choice to start, 'cos it's pretty flexible and quite easy-to-use even for beginners.

Techno and electro need more live-acts!!!
