All very nice, high quality tool suggestions. If I was a contractor and/or did work for a living that demanded a cordless drill or related, I would follow the noted advice.
I'm not a contractor, nor do I have the budget to own the best of all the woodworking tools in my arsenal. In order to own a woodworking arsenal, I have to take the middle of the road for many/most of them. Ryobi is my middle of the road for cordless drills. Specifically, the plus-one lineup. It is 18v, relatively cheap, readily avail at Homey, and been the only cordless drill I have used to build every one of my projects; including the garage/apartment project. Plenty of power, reliable, dropped it from the ladder many times and still ticking, and has dozens of other tools that operate from the exact same battery. The best starter kit would be something like a bonus special at Homey: drill, 2 batts, charger, worklight, 5.5" circular saw, sawzall, carry bag. Homey usually has this outfit for $130 - $150. Christmas specials will be comin, too.
Tip: regardless of your choice, make sure you know the cost of the replacement batt's.
