Two years ago I gifted myself the ryobi 18v combo - 1/2 inch drill, 6"circular saw, sawzall, flashlight.
Love the 1/2" drill (several years back my brother gifted me the 3/8 12v which is going strong and super handy around the house for light duty)
Sawzall is sloppy but okay for pruning trees and cutting PVC (I have my dad's old craftsman jigsaw for fine work)
Flashlight is... well, a flashlight.
Circular saw seems to burn through battery life.
Fortunately I have a 4 1/2" corded Makita... and a 7 1/2 inch worm drive Milwaukee that weighs about 20lbs
