First, i apologize if this is already being discussed on another page. If it is, please point me to where. I want to get my son a Keurig for Christmas, but, have no idea which one. I am way too cheap to buy the little k-cups, but, at 21 yo, even though he never has money for food, he always seems to have money for coffee. Any recommendations from users? Also, (and most important), which store has the best BF deal? Thanks!
