I don't think people pay that well for used camera gear. Nobody wants last year's model for the price of this year's model, even if it still takes good photos.

I don't think people pay that well for used camera gear. Nobody wants last year's model for the price of this year's model, even if it still takes good photos. In my case, I wanted to sell the previous model of a camera after the new one came out. To upgrade, of course. They offered about $100 on a $400 camera, and sold used ones for about $300. That's a big cut, so I decided not to upgrade and am perfectly happy. My time to make a listing somewhere, collect offers, vet a one-off purchaser, and pay for shipping was probably more than $200, so it was actually a good deal. It's not a good deal if you operate at scale and can get the efficiency up, however. So if you wanted to start a business, you could probably eat their lunch. (Or fragment the market and put everyone out of business!) I mostly buy old film cameras used from them. People selling them on eBay bought a custom-made 4x5 camera for $6000, don't want it anymore, but can't bear to see "their baby" go for less than $5999. People selling to B&H are less emotionally attached so the prices are better.
