Keurig can't be described as "mess free." We have one and work and the machine spews coffee all over itself and, of course, the place you put the pods and the spout gets all gunked up and nobody cleans it. It's pretty gross. Same thing happened with the old one so it's not just one model.
>Maybe in a non-coffee drinking house where guests occasionally want one cup.
I have a $20 drip pot that makes 1-2 cups and takes up a quarter of the counter space. French press is even cheaper and I have one that makes only a single cup. Then there's aeropress...
