I'll provide a 4th bump for Mike's Hitachi. That thing is great. The drill is basically light enough to justifiably be used as a cordless screwdriver / light duty jobs as needed, and the impact is amazingly useful for just about anything you would spin on or off with a socket wrench.
From a durability perspective, I LOVE my DeWalt 18v drills, though. I drilled EVERY hole for every wire in my new garage (and there's a LOT of them) using either the basic or right-angle cordless. Had them for at least 4 years now, and with 2 batteries you always have charge (unless using the circular saw - that drains them quick). Both have been dropped from ladders multiple times, and both have torque to spare, enough to nearly break your arm if you happen to bind a 4" hole-saw up. Mine aren't even the XR ones (which I think have stronger gear housings).
I've personally had good luck with Goodyear and Greatneck 24v impacts from Pepboys as well ($60 on sale). First one (Goodyear) lasted 5 full years of AX+RX tire changes. Second one (Greatneck) breaks lugs loose just as well. These are on the bulky side, of course, but with battery removed still fits in my mobile/track tool box.
+1 on the cheapo Goodyear. I've had mine for about 3 or 4 years and while it doesn't have the ultimate power of the Dewalts it works fine for the price. I break the lugs with a breaker bar.
