I know I'm really late to this thread but I have recently enabled my instance of squeakroad and set up marketplace where users can buy/sell all types of watches. You could be the first one to set up your vendor account here: http://tf6utnjwa2oqnm4hfn3eofbfidfikviathmf7c7bhmxcrh2gimcdveid.onion

Also shout out to @yzernik for this project!
