I have been brewing for just under a year and brew 2 gallons at a time. Chose small batch brewing to learn the process and to try more styles of beer. Here is what I use for my mash tun http://www.homebrewstuff.com/2-gallon-mash-tun.html but I'm sure you can make your own. I converted a 2 gallon water cooler to a hot liquor tank and fly sparge with it. When sparging I cover the mash tun with an aluminum pie tin (high tech!) with holes punched in it. This disperses the water coming in from the hot liquor tank so that there is not channeling in the mash. Thus far it has worked well for what I have brewed, my favorite being a bourbon vanilla porter. I'm considering jumping up to 3 gallons with the same set up.
