Keurig-type Coffee Maker (Downers Grove/Darien border)

Seeking a Keurig-type/pod-type (prefer with adapter to use ground coffee but not deal breaker)/single serving coffee maker in good working condition. Brand, color not important, but need smaller machine/smaller footprint. It's for my elderly, sick mother. (We can't afford..both disabled, live on Social Security.) Thanks in advance.
