I am thinking keeping a small stock of three beers on hand. The three beers are: Sierra Nevada Stout, Starr Hill The Love, and Smuttynose Finest Kind IPA. Each of these is reasonably priced and a good example of the style. The diversity of styles and flavors would let me find something to match almost any occasion or food.
I would plan to supplement my standards with some occasional treats and seasonal releases. Some highlights would include: Weihenstephaner Hefeweissbier, Founders Imperial Stout, Bigfoot, Hibernation Ale, and a variety of Belgian ales, sours, and gueze.
