Rockwell Tools via eBay offers the Rockwell 3rill 3-in-1 Impact Driver, model no. RK2515K2, for $49.99 with free shipping. That's $25 under our mention from last month and it's the best price we've ever seen. (It's also a current price low by $22.) It functions as an impact driver, screwdriver with 22 clutch settings, and 2-speed drill. It comes with two 12-volt LithiumTech batteries, a charger, carry case, power-screw driving bit, and participation in the lifetime replacement battery program.
Of note, this item is listed as new-other which means the tool is new but has been re-boxed in a plain brown.
