Well... shame you don't like Milwaukee. They have been getting high
ratings in the reviews lately. They basicially have the highest torque
for the volt size across the catagories. They also have a great chuck.
Plus, I think the new ones also have a reverasable battery so it can
get into some tight spots easier.

I'd say Milwaukee, Festool or DeWalt. Festool has some cool switchable
chucks for offset and right angle, very cool stuff.
