Where can I buy the machine that brews coffee and tea without a pot?

I'm looking for that little machine that dispenses coffee or tea without a pot and all that mess to clean up in an area without a sink. I saw it in the waiting room at the car dealers but can't find it in the stores. You set your cup under the spout, then put in the little containers with coffee or tea into the receptacle and close the lid and, Voila! It dispenses the beverage of your choice. Which stores carry this? No one seems to know exactly what I'm talking about but I swear I've seen it before. I'd appreciate your help.
