CPO Outlets via eBay offers the refurbished Makita 18-volt Compact Lithium-Ion Cordless 2-Piece Combo Kit, model no. XT257M, for $219.99 with free shipping. That's the lowest total price we could find for a refurb by $60. It includes a brushless hammer driver drill, cordless impact driver, two Li-ion batteries, 15-minute rapid charger, and tool case.
A 1-year warranty applies, although it's unclear who backs it.
