I absolutely love Yuengling Black & Tan and am very sad we don't have it on the West Coast. A lot of the mid-range stuff is pretty good though, with Samuel Adams and Shiner in there. Samuel Adams has excellent Oktoberfest and Winter Lager brews to their name, and the standard Boston Lager isn't bad either. When its on sale, Gordon Biersch stuff is also really good, depending on your tastes. They have the excellent Maerzen autumn beer (normally spelled with umlauts) and their Blonde Bock is a hell of a summer beer if you like your beers a bit on the hoppy side.
