Ours has a cabinet under the counter, all to itself. It sits on a sort of shelf; to use it, you open the door and pull the shelf up to counter height and locks into place. To put it back, I just have to hold the shelf and push in a lock button on the side and guide it back down in the cabinet. I've finally learned to do it without smashing my finger, lol.
DH's grandma had that put in when she lived in this house, and she has a much nicer one in her new house.
