I was at Sam's Club here in Philly yesterday and they had 21.6 & 19.2 volt cordless Kawasaki drills for $40 & 30 respectively. I don't know how good the brand is, but it appears that they come with an extra battery. I've got too many cordless drills already to purchase another to see how it works, but it could be a good deal.
YMMV,
