Refurb King via eBay offers the refurbished LG 12,000 BTU Portable Air Conditioner for $239.99 with free shipping. That's the lowest price we could find for a refurb by $60. It features a timer, 400-sq. ft. cooling area, and oscillating air vent. A remote control is included.

A 90-day warranty applies but it's unclear who backs it.
