I have one (a cheap one from the store), and use it at work (there is a Kuerig there, but it makes horrible coffee). If you pour a little to get the grounds wet, wait a few seconds to a minute, and then pour your hot water, the coffee is good. I just use a regular, small filter and fold it into a cone shape--much less expensive.
I have a nice espresso maker and a french press at home, but the pour over is fast enough and easy to clean.
