I am a single person who lives alone....since I don't need a 12 cup coffee maker, I've been attracted to the single cup coffee format.
My first purchase of a single cup coffee maker (I refuse to name names# was a complete disaster...it made poor quality coffee, the coffee cartridges were not available anywhere except at the manufacturer, plus they were horribly expensive to purchase. After that, I decided to wait for awhile for better technology to come along.
A couple of years ago, after I felt the tech had significantly improved, I looked at single cup coffee machines again, and decided on the Tassimo T-20 model....it made great coffee, the T-Disks could be purchased locally, and were reasonably priced, which I felt would more than make up for the higher cost of the brewer itself.
I have owned this model for two plus years now, and it's hands down the best coffee machine I've ever purchased. The coffees even better than 2 years ago #which wasn't all that bad even when Starbucks left the format#, coffees are still reasonably priced and locally available at more places than ever. I even developed a taste for lattes and cappuccinos...oh those are so good #real milk makes the difference)!
This machine can do everything, do it better, and save you money over the long haul.....what is not to like about it?
