Basic Channel/Maurizio etc is too dubby/gentle for me. I've got a few things from the Force Inc label, Klang etc. Tracks like "Tod eines Hippie Maedchens" by Reinhard Voigt are just superb.
You're right with some Villalobos stuff; he can get too jazzy sometimes, but when he gets glitchy/clicky it's superb (I love his remix of "Kiss tomorrow Goodbye" by Auch).
Just downloaded the Daniel bell album last night, and some of that is wicked. Really minimal, literally just beats and beeps. Good stuff!
