I just actually got my Keurig yesterday. The website I brought it from had it up for $59 compared to $99 at Walmart. Yes it is refurbished but it comes with the standard warranty so I'm not too concerned. I've used it twice and it's worked just fine. I love the pumpkin spice k cups. You can also go to Keurig's website and find sample packs that you can buy. That way you don't buy 18 kcups of 1 flavor only to find out you dont like the flavor!
I bought a Keurig for my Dh for Father's Day. He dearly loves it. I have a hard time finding different flavors for it, though, in stores. Would like to find a store that carries the hot chocolate, etc.
Looks like Keurig actually puts out the Mr. Coffee machine too...apparently they partnered up to make it. It is considered an entry level keurig. One of the reviews I read said it can fill a cup fine, but not really a thermos. Not sure if that is any different between the two.
