i got a keurig coffee maker for xmas. i am cheap. the idea of single shot brewing $$ annoys me. i read that the keurig style unit can use a plastic ground holder to use bulk coffee. sounds plausible but the 1 shot reuse function sounds annoying also. i am a 1 pot person. i want 4-5 cups, not 1. i also do not want 2 coffee makers on my counter. should i return keurig?
