I strongly encourage everyone to vote for Innistrad. The box is recently out of print, but the set contains Liliana of the Veil, Snapcaster Mage, and Geist of Saint Traft; three cards that will see extensive play in Modern, Legacy, and even Vintage. Also, Innistrad has been one of the most well-received draft formats of all time. I anticipate boxes of these to be +$150 by this time next year, and easily hit $200 when in the next couple years.
