If you're starting small then a 7 litre stock pot. a spatula, a large funnel, small jug, sieve to fit in the funnel, demi john, bung and airlock, piece of tubing, some yeast, some sterilising powder and some yeast. That will get you sorted with the basics to brew 1 gallon batches of most fruit wines or a mead. Just add your honey or your sugar and fruit. Oh and water of course!
If you want to get fancier then you can look at hyrdrometers, filters, bottle washers, heating pads, a whole host of chemicals and additives, larger fermenters and buckets etc.
If you're looking for a book then the booze for free one isn't too bad.
I second that the process is incredibly addictive. We don't drink much but we brew silly amounts. Our friends and family have gotten used to getting bottles for birthdays, christmas and pretty much any gathering!
