These are getting near Leica prices due to all the Japanese collectors dumping them onto ebay. The average seems to be $300, w/ tax and shipping around $350. You can look at the completed and sold listings on ebay and get a feel for the prices. They're one of Canon's best lenses, and in a comparison I saw very little difference between the FD 85 1.8 and the Leica R 90 Elmarits and Summicrons, although the Leicas probably focus closer, and there's nothing else w/ the build quality of the Leicas. My favorites are the early models, but they're heavy. The new FDn glass is exactly the same but in much smaller and lighter bodies.
