Is it that you are looking for? (just an example; item is already sold)

I would go for ebay Kleinanzeigen, as sechser already mentioned.
Could be a lot easier, if a forum member in Germany buys it for you and then ships it to the US.
Not every seller on ebay Kleinanzeigen (the german craigslist) would sell outside Germany (or even the EU).
If you need any help - I am happy to assist.
