Mosinnsgant, on November 2 its Learn to Homebrew day (check main AHA page go to events and click on learn to homebrew). See if there is a club or Homebrew shop particapting by you and ask to tag along I'm sure you will be more than welcomed and it gives you a chance to see how little or how crazy you can go.
Like the others said it depends on what you make your prioerties. You can start buy just making a better beer selection, than improving food, than bring brewing in. Take baby steps . If you try everything at once you'll make it harder see your family. Good luck
Phillamb, the answer is maybe the questions are How much do you need to produce. Is the opening large enough to get a brewing system in there and how high are the ceilings. Than does it have water, power, gas. You need to make the system fit your needs.
In the corny lid take the vent out place a bung with your bubbler or blow off tube in it. Some people also take gas fitting off and do the same. While your at it take 1 inch off the dip tube then when you want to transfer (replace gas fitting or vent) hook up co2 with low pressure and transfer to another keg.
