CPO Outlets via eBay offers the refurbished DeWalt 20-volt MAX 2-Tool Combo Kit, model no. DCK280C2R, for $139.99 with free shipping. That's tied with our mention from a week ago and the lowest total price we could find for a refurb by $25, although we saw a refurb for $5 less last April. 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.
