I'm always amazed at the price some ebayers are asking for their equipment. Just for the fun of it, I did a search for a Canon 500mm F4 lens. I found a new one on ebay for $6200 plus $173 for shipping, with a Hong Kong warranty. I then checked Amazon.com and found their price at $5552 with free shipping. That's over $800 difference. Evidentally, they must get these prices, eventually. People have got to shop around more. This isn't that uncommon.
