I'm a big fan of...

Killians Irish Red (actually drinking one right now)
Blue Moon (and Full Moon, incidentally)
Sam Adams Boston Lager
Guinness stout from the tap (by far the best stout I've ever tasted)
Harp Lager
Shiner Bock

There are some others but they slip my mind right now.

Anyways.. back to drinking this Irish Red.
