I suppose the obvious ones are people like Mark Broom, Carl Craig, Sterac and Luke Slater.
Surgeon can turn his hand to many styles as well... for me 'Balance' is one of the most complete techno 'albums' (in the traditional sense) I've heard. I really liked Johannes Heil's 'Illuminate the Planet' too... but for sheer multi-facetedness (?), I can't think of anyone better than Aphex Twin.
