I've also given up on selling via CL because of the scammers. Now I donate to the local Goodwill or other charity (women's shelters want cellphones, for example), and take the tax write-off.
These devices are absolutely simple for scammers to work with. They're high value, cheap to post, and can easily be swapped with phoney/broken identical devices.
