Keurig K-cup machine

We’ve got a new Keurig coffee machine and it’s awesome. Been trying  out some coffee. So far the self-filled k-cup filter is not so hot, but I don’t think I have the grind right. We’re looking for some decaf, too, so I’m reviewing the decaf k-cups here http://www.greenmountaincoffee.com/mainlayout.aspx?ck=1&DeptID=OurCoffees&CatID=KCup&SubCatID=DecafK-Cups and also watching this new site which is pretty cool http://TheBestDecaf.com. They cut a k-cup in half  and are studying the coffee contents.
