New Beer

I need to replenish the oat soda supply for Clanarchy Skills & Drills tonight (if you're drinking, come join us for some Rainbow Six).  Last week I tried something new, some of that Miller Chill stuff.  It was OK but the lime was a bit overpowering.  What new and exciting beer should I try for tonight?  Guinness is my standard but lately I've been trying to branch out a bit.
