I have always had good luck with the big eBay. Check the satisfaction rating of the sellers and only go with those sellers of 99% or more. And a large number of transactions. Check return policies, and pay with PayPal for return satisfaction.

I've used KEH a few times and been quite happy with it. I also traded in several lenses that I had decided were too heavy for me to use. I didn't get great prices for them, but at least I had some credit toward the one I bought and now use as my walk around lens. They seem to do a good job with cleaning any used equipment and they are accurate, I've found, in describing the condition that the equipment is in.

Then again I bought some Chuck Taylors from Ebay and they were absolutely counterfeits.
