I might catch some for saying this but we use Dewalt and Ryobi. That said, I find myself picking up our Ryobi stuff more often. They are the 18v lithium-ion with the larger batteries. I find the battery life to be very good and have not found a single job at the shop it couldn't do; can't beat the price either. Some people will probably say the quality is low but we have had great luck with them so I can not hate on them. That being said, I own Dewalt and Makita at home and love them to, just way more money invested. I really find myself using the hand drills/drivers less and less. We have a couple nice drill presses, and using rivets, we do not need a driver as much. I would strongly recommend getting one of the nice 12V sets and then investing in a very nice vise for your drill press. If you can use the drill press, use it over the drill.
