Personally, I went to a Keurig about 4 years ago. I will drink at least one... and sometimes two... 16 oz cups in the morning. And, I drink another 16 oz cup in the evening. My coffee is always brewed fresh when I want it. The pods can be expensive. Specials at BB&B, etc. will get them down to 40 cents and I get a 16 oz. cup out of one pod.
For the most part, I use the less expensive ground coffee. I like a very dark roast and buy the "robust" blends or one called "Black Silk". Have the plastic mesh container that I put the ground coffee in and slip it in the pod holder.
If you need the full 12 cup capacity, it gets dicey. Out at our pro shop, we have tried Mr. Coffee, Proctor/Silex, Black & Decket and NONE seem to last very long. We have just made the switch to a supplier who will provide us with a Bunn commercial unit if we purchase the "bags" of coffee from them. If you add up what we've spent in "throw-a-way" brewers over the past couple of years the bags with the Bunn will be a good deal.
Have noticed over the past year or so the number of professional offices, auto dealership shops, tire shops, etc. who have gone to a Keurig in their customer waiting areas. The staff doesn't have to worry about cleaning up a pot where a dab of coffee has "fried". The customer can always have fresh coffee by simply dropping in a pod. It's just cleaner and more customer/staff friendly than the rancid coffee from a pot that has sat there on the burner for a couple hours.
