I noticed that Bed, Bath and Beyond was selling the Deluxe Mr. Beer kit for 50% off this weekend, so I decided to spend $15 and get one on Saturday. Then, I decided to get twelve Grolsch style swing-top bottles from Beer at Home.
This blog has a blow-by-blow description (with photos) of the process. Now I just have to let the beer ferment for a week, and then bottle it.
