I love my Aeropress, but an arguably even simpler option is something like the Hario V60 (http://www.amazon.com/Hario-V60/dp/B000P4D5HG/). $19, and no plastic if that matters to you. I think the filters probably cost you a bit more than the Aeropress.
IMHO you should have several different coffee brewing methods at your disposal :-)
