I have nothing but good reviews for this
Dewalt drill.
It runs every year from between $99 to $169... and right now it is at a low of $99.
It has plenty of power to handle the toughest jobs... recently used it to punch a 2.5" hole with a holesaw into a 1.5" thick wood butcher block countertop. I've used it for mudmixers in sheetrock work... as well as driving an 18" long 1/2" ship bit through two railroad ties.
The battery life isn't superb... maybe 100 3" screws in a row? But it will quick charge back up in 30 minutes... and it comes with two batteries.
I bought one for myself 4 years ago I still use, and I got two for my team last year. I can't say the other brands aren't great.. they might be, but for a nice LIGHT drill that has more power than any FRC team would need, you can't go wrong with this one.
