Amazon offers the Household Essentials Iron 'N Fold Floor Cabinet Fold Away Ironing Board in White for $208.61 with free shipping. (Wayfair via eBay charges the same.) That's the lowest price we could find by $91. It mounts to the wall and features an adjustable height.

Update: The price has increased at Amazon; however, Wayfair via eBay still offer it for the same price.
