There is an ebay seller in Switzerland, ebay id Alpstern, Tobias Gnaden who has a good number of items now up for sale on ebay. Some of them are being offered with attractive buy it now prices like a NOS Nuovo Record front derailleur for 20 euros. I have already dealt with him and he was great to transact with. He accepts ebay and ships quickly.
