Mr. Beer is the crack cocaine of homebrewing.
A lot of people on this board started with one. (I started with a Mr. Beer kit back in 2002.)
You can actually get some decent beer out of a Mr. Beer kit if you disregard some of the Mr. Beer instructions
and go with these that I posted on the RealBeer.com forum several years ago:
(Note that I heard that now Mr. Beer kits now may come with Wyeast smack packs. If so, that's an awesome yeast so it's more than ok to use that if its in your kit).
