Something you may think about getting is a Mr. Beer kit. I believe the little barrel thing is 2 gallons. The kits usually run 30-40 bucks, plus you'll get some kits to try. It being after christmas, you may even get some on clearance. If not, I am sure you can just pick up the barrel for dirt cheap on craigslist or ebay.
