The Millenium Falcon is approx 1.3x1.6 cm in size, and is 1:5000 scale. I obtained mine from Studio Bergstrom for the whopping price of $1.70! http://www.geocities.com/Area51/Meteor/4155/thumbs/orderform.html
It is nicely detailed white metal, very solid and durable. I would rate this ship as a 9/10, deducting '1' for the underside not being very detailed. This seems purposeful, not sloppy, as it's meant to be looked at from above. The sides are fully detailed, however. I STRONGLY recommend purchasing this piece for your SW fleet. At this price, anyone who wants to play more 'in scale' with their WoC fleets must have it!
