I just bought a french press. Since I'm off dairy, I had to give up my daily latte's. So far so good. It's a three cup press, enough for one (large) cup of coffee, a shot of vanilla nondairy creamer, and I'm set to go.

Cost?

Press - $10
coffee - $9
creamer -$2

Lasts me about a month. Times $4 latte by about 25 days a month, and I'm coming out ahead.
