I have the exact Keurig K45 version pictured. Its just great. A perfect single-serving of excellent coffee every time! Only drawback is the cost of K-Cups. A Sam's Club or Costco membership helps with this. Buy bulk and supplement with sale-priced 18 packs of other flavors from the local market and you are golden!
I don't drink coffee, except when I really need it, so this thing is a goddamn LIFESAVER. But a Costco membership will also (unfortunately) be necessary, because currently I am dishing out Too Much Money on K-cups.
