Adorama was about fifty cents on the dollar. The only plus was it was a done deal if you accepted it. If not, they just mailed it back with no worries. Craigslist was the best option for me on that lens. I only had one try and cut the price in half. Just tell them upfront that the price is firm. $360 seems to be the going rate. FM is decent too so long as you know who is buying. I've not used them but others have.
