Most corded drills are pretty large though. I have 12v, 18v and corded drills and would never use the corded drill for small things because it's too clumsy. 12v for small things and 18v for small-medium, corded for large only. I often use both, 18v for drilling and 12v to put in the screws. I'd say buy an 18v as your only tool first, but if you ever start on a project where it's struggling even a little, get a corded drill. They're good bang for the buck at ~$30.
