Went for the set that Dogmush linked to. I was waffling between it and a $399 set, the difference being a heavier duty hammer drill and the 60/20v flex batteries. In the end though, while I am using a hammer drill more often, I still use a drill 10X as much, so decided I didn't want the extra weight.
My 18v hammer drill is heavy duty, so I can keep using that for a while, and when I was looking at the cordless kits, I shuffled over a couple of steps and saw that I could buy a big ass corded hammer drill for like $100. I'll probably go that route when the 18v batteries finally bite the dust, since 99% of my hammer drill work is near power.
Otherwise, this kit looks nice, and I've got a couple of small things I can use it on tomorrow. I am curious to try out the impact driver for construction screws.
