Kelly - They are pretty neat but, IMO, the cost of the little coffee packets would not justify it. At $60 for 108 of the K-cups, you could buy a lot of regular coffee for that price. In the long run, it may end up costing you a lot more.

We buy the big 2 lb containers for around $7 and it says it makes 270 6oz cups of coffee. Depending on how much you drink, 270 6oz cups could last 270 days and, if I did the math right, would cost $0.025 per cup as opposed to $0.55 per cup with the Keurig.
They do make smaller coffee makers (4 cup) that work real well. I like the Black & Deckers as we have one that lasted over 10 years. We had to get a new one because would couldn't find a replacement carafe for it.
