For Sale: One Shuttle, used.

From New Scientist:

Space shuttle for sale, fully loaded, air conditioning, one careful owner. It's the ultimate bargain. NASA has cut the price of a space shuttle to $28.8 million. The vehicles will go on sale after they finish constructing the International Space Station, scheduled to be later this year. The New York Times reports that NASA had hoped to get $42 million for each vehicle but lowered the cost in the hope of sealing a deal. It has three to sell, although one of these, Discovery, is already promised to the Smithsonian National Air and Space Museum in Washington DC.

If an entire shuttle is beyond your budget, consider a main engine instead. NASA had hoped to charge up to $800,000 for these but lack of interest has forced it to slash the price. They are now available for free: a bargain in anybody's language. Just bear in mind that the buyer must pay for postage and packaging.
