K Cup recommendations

[LasciviousXXX]

My work just purchased a Keurig machine for the office. I generally drink Espresso but it isn't easily available at work LOL. So I'm going to pick up some Kcups to try 'em out. I don't use sugar or cream in my coffee so I love full flavored cups of coffee. I will try out some of the ones recommended in the thread. However, are there any specific rec's for someone who generally only drinks Espresso?

Thx
