Cheaper alternative to a giant butcher's block:  this cedar island with a slate top.  Technically it's cedar 2x4s reclaimed from a pickles and peppers factory, topped with an antique school chalkboard (which is pretty much nostalgic/green porn).  The little shelf on the bottom, though absolutely wonderful, may pose a problem with children.  I like the idea of a slate top.  It seems only second to white marble for me.  Third actually, because a butcher's block would come first.
