I am a big coffee drinker and I have always wanted a single serve coffee machine because I think it tastes much better than the alternatives. I never got one because the machine is usually pretty expensive and the coffee is even more expensive than regular coffee.
If I wasn't moving soon I would consider getting the Mr. Coffee machineMr. Coffee Single Serve by Keurig, which is $59 (regularly $79) but I would only get it along with a Refillable Cup so that you can refill the coffee with your regular coffee.
