K-cup cost is definitely a consideration. The wife and I down 3-4 cups each morning just to stay ahead of the kids.
I'm thinking about using the dead space on the right side of the entertainment center. I think there is room on the center's narrow side panel to install an additional outlet and then either mount a small shelf or find a wall-mountable coffee machine. That space is still clear when the slide comes in. Just need to determine if there is a stud behind the wall somewhere.
