Got the Makita 18v ratchet, has both a 1/4" and 3/8" head. They also have a 12v version, but the tool is the same size aside from where the battery attaches, so I went with the 18v model. Makita's current promotion gave you this for "free" with the purchase of the 2x 4.0 amp-hr battery & charger (& bag) kit, so that worked out nicely. Used a similar promotion when I got the 1/2" impact wrench, so have plenty of batteries now.
