Drills for ~$100

I'm asking mainly because we have three drills right now; two do almost everything we need, and one is close to worthless. It simply stalls when given difficult tasks where the other two won't given they have enough battery.
I want to know if there are indicators that I can use to avoid getting another worthless one. If all I need to look at is brand, then that's good to know. I was going under the impression that a 12V Black and Decker would be a better investment than a 7.2V DeWalt, but it looks like everyone has just recommended that I look at brand over specs. I'm also assuming that Amperage is the most reliable factor when looking at corded drills, but if I should ignore that and focus on brand instead that makes things easier. A 4Amp Makita is a lot cheaper than a 10Amp Skil.
