Pretty much any 18v battery drill will work fine. Main thing is, give your stab jacks a liberal spray with spray lubricant and don't go too fast. If the jack binds up, it can snap your wrist in a heartbeat. Have a firm hold and just ease the jacks up and down, being prepared to stop if it binds at all. I spray my jacks about every 3rd trip or 3 months, whichever comes first.
Also, if you buy one of the chucks that fit the end of the stab jack, get one that is flat on the sides. The completely round ones will sometimes spin in the drill. Had one of those and left it at a campsite on purpose. Sorry if your the poor guy that picked it up and it's aggravating now ;-)
