Quick check on eBay Germany, there are 2 less than that price and one looks really nice, described as "Nokia N900 - Schwarz Smartphone 32 GB Type RX51"
Just ask the seller if it is still starting up.

The cheapest one at 55 Euro is dirty but working , but USB broken so lots of effort for a beaten not broken copy.

Other than that, the question has been generally answered as "PM Meamish"?
