CPO Outlets via eBay offers the refurbished DeWalt 4-Tool 18-volt Cordless Combo Kit, model no. DCK425C, for $149.99 with free shipping. That's $29 under our mention of a new kit from last month and $97 below the lowest total price we could find for a new one now. It includes a compact drill/driver, impact driver, cordless reciprocating saw, pivoting head flashlight, and DeWalt bag.
A 1-year warranty applies, but it's unclear who backs it.
