Buy one Freak, it's $30 tops, plus a bag of coffee. You can get elaborate with a bean grinder and whole bean coffee, but it's not really needed for a good cup of coffee.
I was hooked on K-cups for years, it gets expensive after a while, considering how much coffee I drink in a days time.
I bet you'll love it.

So finer grind for seepage issue, huh?
I drink coffee black, too. Just depends on what kind of coffee I get. I found a killer Costa Rican bean that I love black, but my local coffee shop doesn't brew it often.
