Lion's Head is a great no frills beer. Prob the best tasting, cheap beer I've had. (Brewed in Scranton)
Most things from Troeg's, Bell's, Brooklyn, Sam Smtih or Victory breweries.
Victory Golden Monkey
Christmas time(Troeg's Mad Elf) is awwwwwwwwwwesome and will put you on your arse.
Sam Adams Cherry Wheat
Sam Adams Lite is the best domestic light beer imo, but it's $30 a case, which is steep for a lite beer, but it's really crisp.
Miller Lite is my "I'm going to be drinking all day" beer.
