CPO Outlets via eBay offers the refurbished DeWalt 20-volt MAX 2-Tool Combo Kit, model no. DCK280C2, for $159.88 with free shipping. That's tied with our mention from last week as the lowest total price we've seen for this model. (It's a current low for a refurb by $30 and $69 under the best price for a new unit.) It features a 1/4" impact driver and a 1/2" drill/driver.
A 1-year warranty applies, although it's unclear who backs it.
