For drilling, I have a Porter Cable 12V that I've had for about 7 years now. It still works great but it is getting close to time to have the batteries rebuilt. For driving, I used to have a Dewalt 12V that I loved, that is until the smoke came out of the batteries. I replaced that with one of the new Lithium Ion Bosch drivers which is also great, but doesn't have the power of the Dewalt.



I'll have to go dig mine up and take a couple pics.
