K-Cup guys...

[Blak Smyth]

I do not reccomend those use your own cups. I tried them and they do not work well at all. Keurig only ever worked for me with the factory k-cups. Seemed like water would push straight through and you would get a super weak, watered down cup. The one Bob linked is the one I used. I bought it at "Bed,Bath and Beyond".
