Newegg offers the refurbished DeLonghi 11,500-BTU Portable Air Conditioner for $209.99 plus $2.99 for shipping. That's the lowest price we could find for a refurb by $40. It includes a remote control with large LCD display, and features three fan speeds, and dehumidifies as it conditions.

Note: a 90-day warranty is included, although it's not clear who provides this.
