build a mash tun. 5 gal igloo cooler works well for most things unless your going "imperial" you need yourself a wort chiller, purchase or make your own. after you got yerself a mash tun and chiller, and your boil kettle, you are good to go so long as you have fermentation vessels. everything else is standard (auto siphon (i recommend the half incher), hydrometer, wine thief, air lock's, etc.)
a buddy of mine and i brew at least once a week and we share the chiller/mash tun. we each have our own everything else
