Selling to KEH has been one of the possibilities I've mulled over the past year. I know what kind of prices they would offer, so it would be a last resort kind of thing if I sent it their way.
My local options have been dwindling. Every time I think there is some place I could take them (like a consignment shop), the outfit ups and goes out of business. Ebay is not an option because we all know how one can get screwed by the buyers. I have thought of putting it all up for auction, but it would have to be the right company, as not all of them around here have much experience with photographic gear. My one time before when I sold it all off due to necessity the auctioneer actually asked me to announce all the items as they were presented for bid. That was a painful night.
But anyway, my experience with actually selling to a store was at a camera show upstate where they had some dealer from NYC making offers. I brought some items that were surplus just for kicks. I didn't need the money, but if they funded a camera or lens at the show, then it would be all good.
The buyer looked over my stuff (most of it was Zeiss), and gave me some ridiculously low figure. So I just smiled, thanked him, and started putting the stuff back in my bag. He immediately started to say he wanted to look at it again, maybe he could do a little better. I decided he had blown his first move, and went on my way. He was still asking me to come back as I headed down the aisle. A couple of gents waiting in line behind me also took off after witnessing the transaction.
I don't mind selling at wholesale to someone who is looking to resell it, but when they can look you straight in the face and make an offer that is basically robbery, I don't need to hang around anymore.
