Despite the cost to sell on eBay, I've had much better success than free forums like LL or GetDPI. Specifically, I've sold off items like Hartblei T/S lens, lenses with Rollei electronic shutters, Linhof 679 accessories and Fuji 680 camera systems. In each case, the items had zero serious interest on the mentioned forums but sold relatively quickly on eBay. eBay has such a world wide reach, well beyond the English speaking world served by the forums. My stuff ended up in Norway, Sweden, China, Russia and the US. I did sell a digital back through LL though.
