As someone who has used a Skil circular saw, and owned a Skil cordless 14.4 volt drill, I can tell you that ...
SKIL SUCKS.
I've had the drill for about two or three years now. It only came with one battery, and it only lasts about 5 minutes of continuous use.
If you're not a contractor, but just a normal home owner that would like a solid drill, go CORDED. Trust me. Batteries wear out. And corded drills/screw guns are much more powerful. Also, you can get them for about 1/3 the cost of a cordless drill. Rather than this, I'd rather head to menards and buy a nice Dewalt corded hammer drill. It will last you for the rest of your life, and it will probably cost you less than $100.
