1 gallon doesn't seem like it's worth the effort to me. I do some 3 gallon batches, which lets me do full boils on the stove, is easier to physically manage (less weight), and nets about 2 gallons of finished beer-- enough for 16 pints. I usually use a simple recipe, so the brewday is pretty short. It's a nice break from the usual brew session.
Plus, I can pitch a Wyeast Activator pack directly without doing a starter.
The guys over at Basic Brewing did a video podcast about small batch brewing. They called it "A Six-pack of IPA": Basic Brewingâ¢ : Home Brewing Beer Podcast and DVD - Basic Brewing Videoâ¢ (look at the bottom of the page).
