e57, Makita had a deal at my local tool supply if you buy the new lithium 18 volt 1/2" drill with hammer function you could get a free impact driver. Of course the drill is $350.00. So far I am real happy with it, I've worked all day on one battery. The impact isn't here yet.
Milwaukee has a similar offer on their $425.00 28 volt lithium. Altho I like Milwaukee, the 28 volt drill was very heavy and akward so I opted for the Makita.
