I bought one about 2-3 years ago. I actually bought the hammer drill version. Set came with 2 batteries and a charger. Price was about $119. I like the drill. I like its power alot. Its more powerful than some of the lighter duty 1/2 inch corded drills. There's never been a time when I used it and it could not get through whatever I was drilling. I used a one inch masonry bit with the hammer drill to go through my foundation. I also used it with 1 inch spade bits through rail road ties. It's a beast. I have gone though bricks many times. (Get the hammer drill, if you buy it) The downside is the batteries dont last long at all. Moreover, if you run it down too low, the battery will appear as 'defective' on the charger and it will not charge. The batteries can not be charged hot and they take longer than the one hour advetised time. I have heard there were problems with the chargers. B/t/w, I brought my batteries over to a buddy who has an old charger and even though my newer unit would not charge them, my Buddies' worked. They make a lithium battery for these units now, which i have heard are much better and last longer, but they are pricey.
good luck
