What kind of coffee do you drink? Espresso or drip?
If you like espresso, a Nespresso machine produces a far better cup than Keurig, ainec. Problem is that the pods are sold at very few places (several Bloomingdales) or you have to order online.
Keurig is good if you want the option to drink teas, hot chocolate, etc. If espresso is your thing, I'd avoid the Keurig.
