+1. You can brew more often, more different styles by doing small batches. And if it helps you feel less skittish doing your first AG batch, then go for it. I brew most batches in 5 gallons (personal preference) but have brewed many smaller batches , so remember - it's just as easy and quick to mash for 5 gallons as it is for half that, and you'll have more beer. After you collect the runoff in your pot, it's essentially an extract batch from then on, except that you made your own superior extract. I say memorize dennybrew, rdwhahb, and do what you like. It's easier than you think.
