Now that the Deathstar was desrtoyed...you can own the Throne Chair of the Emperor himself.

The chair will set you back a whopping $5,000, but
that's the price you pay to rule the Galaxy and say classic,
unforgettable phrases like "Now witness the power of this
fully armed and operational PowerPoint presentation!", "Everything
is proceeding as I have foreseen," or "Anakin, could you bring my
slippers and today's paper, please?"
You could have had it signed by the Emperor himself...but, remember,
he's dead!
