what KIND of techno? saying you want techno is like saying you want rock. there are dozens of subcategories. i suggest you start out with House electronica. its easier listening.
some of my favorites include:
TIM TIM
Ladytron (more dance)
Benny Benassi/the Biz
Fischerspooner
Mouse on Mars
Wolfsheim (less techno more rock)
The Chrystal Method (the masters of mix)
