Personally I think the Death star wont gain so much value after it vanishes from the stocks, it will probably jump to 500$ right away and to 600$ after 2 years and to 700$ after 4 years, so not really a very good investment, though there will always be those guys pushing the price (they are buying the sets for high price from each other to increase the ebay price tendency) The Town hall set has already gone from 200$ to almost 400$ in 2 month, so there are way better investments out there i guess..
