I have been thinking about a C12. I am not interested in the belt clip and I think there is an attachable light system Festool offers that works better if one really needs the light?
My big question holding up my purchase is batteries. I am wondering if I should be considering one of the drills with Li-Ion batteries, assuming the new C12 will not offer them? The biggest advantages I know of for these batteries is shelf life and the ability to handle cold without loosing as much charge.
Since I am transitioning between construction type jobs and cabinet making I am thinking: I will be driving far less screws, working in my heated shop with convenient electricity/chargers, more interested in features/precision, a lighter tool.. which seems to suggest the C12 so far.
