Would you purchase a used hitch? Good or bad idea?

ya I would buy it. I had to put a new hitch in my 2017 3500 because they told me my 16k b w patriot would not fit rails. It was a rush idea,i was towing next day after truck was delivered. I put in a 20k reese but would rather my other hitch at least I can pull it out myself. I know my hitch is in good shape had it for sale also 500
