Goose Island is a great brewery that makes good beers that appeal to a broad range of tastes, but with a "craft" bent to them. Since you're in Elgin, you should be able to find most of their products very easily. You'll probably like Honkers Ale if you like Sam Adams lager. Their IPA, brown ale, and oatmeal stout are also all good.
Also, probably generally give the Sam Adams line a break. A lot of their beers are pretty crappy.
