There's a full-sized, original and historic Nantucket Lightship for sale on ebay. The auction ended yesterday at $222,351 but it didn't sell because the Reserve price wasn't met. It had a Buy It Now price of $295,000 but the biggest problem I think is that it's located about 10mi inland from the nearest port, Duxbury, Mass. Someone might be able to turn it into a bed 'n' breakfast type business..
