Best Buy offers the refurbished Honeywell Oil-Filled Digital Radiator Heater, model no. HZ-709, for $22.99 with free shipping. That's $61 under the lowest total price we could find for a new one. Sales tax is added where applicable. It allows you to set the temperature in 1° increments and features a timer, casters, tip-over safety switch, and more.

A 30-day warranty applies, although it's unclear who backs it.
