I love this particular Keurig single serve brewing system since you have a choice of 3 different cup sizes.

If you haven't made coffee (or tea or hot cocoa) in a Keurig coffee maker then you are definitely missing out on a spectacular cup of coffee. Keurig is similar to other single serve coffee brewers but unlike others, you can brew larger and taller cups of coffee.

K-Cups are individually sealed so each cup of coffee is super fresh. K-cups (often called pods in other brewers) are available from many coffee manufacturers such as Coffee People, Tullys, Caribou, Newmans Own, Emeril and many others.

Don't forget to check out the Obama blend from Peoples Coffee (McCain blend is also available)

I just bought one of these a few weeks ago. It's great for coffee (obviously) but it's also great for tea and hot chocolate. I don't actually drink much coffee so I appreciate the green tea that it brews and the hot chocolate that it makes.

The machine is also very stylish on my kitchen counter.

This is the best invention since sliced bread. Individual hot cups of coffee with everyone choosing his or her own flavor.

This is my favorite coffeemaker. It is so convenient and the coffee tastes delicious. I find that I"ve actually cut back on my caffeine intake because of the richness of each cup. Two cups and I'm good for the day. With other coffeemakers I find that I need more cups to get the same satisfaction. And I don't ever get an after taste because it's always fresh. Love it.

I was very grateful to have discovered this coffee maker. It's perfect for someone that wants just a cup of coffee or tea without the whole ordeal. Just pop in the coffee pod and hit start. It's that easy!

I am a Gov. civilian deployed w/the military, and I work in a trailer with no running water. I have been making due with a hot pot of water and instant coffee. YUK. Since I got my Keurig B60 - I have NO more problems. I use the same bottled water and the K-Cups and I have a great cup of coffee! I will be purchasing a second one to use at home, just for the convenience! I would recommend any of the Keurig single cup makers to coffee drinkers that don't want to make a whole pot. It's always fresh and never has the "sat all afternoon taste!" (via Green Mountain)

This little baby is my new best friend. I have a bit of a coffee habit, not too many cups a day but I have to have at least one and it has to be GOOD. My boyfriend got one of these for Christmas and we're going crazy over it. We used to spend $7 a day on coffee at the shop, now we spend less than a dollar a day for the same amount, and arguably better coffee.
The machine is idiotproof, turn it on, wait for the water to heat up about a minute (they say leave it turned on and the water is always hot, but we're power savers) and then pop in a K-Cup (a little plastic cup filled with your coffee) and press the size you want (small, medium or large, essentially). Then 45 seconds later, your coffee is done. But this is seriously good coffee, nothing at all like instant.
Some other great features are that there is absolutely NOTHING to clean, except I could see eventually you'd want to clean out the water tank if you get hard water deposits. You can also buy a special attachment for the machine in which you can put your own grounds, if you have a specific brand of coffee that you like, or if you're trying to keep your costs down (each K-Cup, which makes one cup of coffee is about $0.50). You can also make tea (which I haven't tried... conventional tea is easy enough and I'm not a big fan anyways) and cocoa, which is really tasty.
My only two concerns are first,the amount of packaging that you go through everyday. its not huge, especially compared to a take out coffee cup and disposable everything you find at starbucks and such. When the coffee is done brewing, I rip off the foil lid and discard it, toss the grounds into my compost, rip out the teabag-like liner and compost it as well, then throw the little plastic cup into the recycling. I feel a bit better about myself. The second is that in my area, I can only find the "K-Cups" at one store, and they only sell four kinds. Fortunately, they're all super good kinds. I've also found websites that sell them for the same price and will ship for free if you order four boxes or more (18 cups to a box) so thats fine. There are over 200 different coffees you can order, so you'll never run out of options!
Anyways, I HIGHLY recommend investing in this if you like coffee and want to save money. It will pay for itself within the first couple of months and will make you very, very happy. And very, very caffeinated!
