Incidentally. Has anyone else tried mini keys? Look to me to be a cost effective solution? Even better for real ale I'm thinking.
I use Tap-a-Keg... two of their 1.6 gallon bottles collects most of the batch... the other 80 or so ounces I bottle. It was easy, inexpensive, and easy (did I say that already?) The tap system has changed recently, they use a single 16gram cylinder (mine has 2 8's)... but the system works great.
Don't over carb (I think someone mentioned what happens). I believe it's 1/3 cup of primer for the 5 gallon batch. Works great.
