Stanley Tools via eBay offers the refurbished Bostitch 18-volt Lithium 2-Tool Combo Kit, model no. BTCK410L2R, for $79.99 with free shipping. That's $103 under the lowest total price we could find for two new tools sold separately elsewhere. This kit includes the Bostitch 18-volt 1/2" Lithium Drill/Driver, Bostitch 18-volt Cordless Lithium-Ion 1/4" Hex Impact Driver, two Lithium Ion batteries, and 18-volt Lithium Ion charger.
A 30-day warranty applies, but it is unclear who backs it.
