It's not just the Ultimate Lego Star Wars collectible. It's arguably the most desirable Lego set in existence. Clocking in at 7,541 pieces, the new Lego Ultimate Collector's Series Millennium Falcon is the biggest Lego set in history and comes in a box to match. Insanely detailed, it has multiple interior sections, can easily be swapped between the configuration seen in The Empire Strikes Back and the one from the new trilogy, and as such comes with ten minifigs representing the crew members from each — including both young and old Han Solos. Should its price seem like a deterrent, consider that its predecessor, released in 2007 and missing over 2,000 pieces from this set, consistently sells for over a grand on eBay.
