Thanks to the United States government, we know that the cost of building the Death Star will be about $850 quadrillion (or $852,000,000,000,000,000 if you want all the zeros spelled out for you). Suppose that you want something a little smaller, faster and more nimble. You would be looking for a YT class Corellian freighter, perhaps even the Millennium Falcon. Fortunately, building a Millennium Falcon is much more affordable and operating it is a positive bargain.
To find out how much your own Millennium Falcon will set you back, our friends at Varooma have put together a handy infographic for you.
