I recently purchased the new Keurig B-70 Gourmet Single Cup Home Brewing System that was released on October 1st, 2006 and have been very happy with it. The machine is extremely well designed, simple to operate, aesthetically pleasing, and most importantly, brews an excellent cup of coffee. I am very impressed with how quickly it is able to brew a cup of coffee, the selection of brew sizes, and how simple clean up is.
There are a variety of single cup brewers on the market now, many utilizing pre-packaged coffee "pods" for brewing. Personally I was not comfortable purchasing a product where I would be locked into the selection and pricing of a specific manufacturer, or one that would only brew coffee and not tea and cocoa. This is just one area where Keurig really shines above their competition.
Keurig has gathered support of a variety of gourmet coffee, tea, and cocoa manufacturers and there currently there are over 140 different types sold pre-packaged in K-Cups including Green Mountain, Diedrich, Gloria Jean's, Timothy's, Van Houtte, Tully's, Coffee People, Newman's Own, Celestial Seasonings, Bigelow, Twinings, and Ghirardelli. Not only is there a large selection to choose from, there are a variety of resellers online offering K-Cups, and pricing is extremely competitive.
In addition to the pre-packaged offerings, Keurig offers the My K-Cup Reusable Coffee Filter allows you to use your own gourmet ground coffee in your Keurig home brewer. This option provided the extra level of comfort I personally needed to make the jump into a single cup brewer. Frankly I don't find myself using it very often as I had originally thought, as there are so many options available in pre-packaged K-cups.
The pricing of the Keurig brewers are extremely reasonable, and brews gourmet coffee in just a fraction of the cost of purchasing it from a Starbucks, Coffee People, or similar. I expect that my machine will pay for itself in savings in just a couple months of use.
The only suggestion I have for Keurig is that the My K-Cup Reusable Coffee Filter be included with the sale of the brewer, and not an optional accessory. It is such an inexpensive accessory that I am surprised it was not included. Overall the Keurig brewers are excellent value and quality and would recommend them to anyone interested in a single cup brewer.
