I personally LOVE EBAY! I picked up 80% of my FD/FL lenses there and for a song. Maybe I've just been really lucky. Now that I have tentatively stepped into "autofocus land" finding a deal by my super-cheapo standards is a lot harder but still I managed to score a pristine Elan 7e for $100 less than what I could buy it for locally or at online stores. But I can't bring myself to sell anything on it. Which is why I have FD lenses that I can't use so if you are interested...
