I've been an active eBay member since the beginning and it's changed so much over the years (good and bad) that I only buy new items there , never sell anything and never, never buy used amateur radio gear. I've only been burned on used ham gear on eBay and never in a private deal, eHam or QRZ. eBay sellers have some standard verbiage to cover themselves and make it easy to sell off non-working gear. Saying things like "untested" or "have no way of testing", "worked when taken out of service", etc., etc., etc...all of which make it easy to avoid a PayPal claim down the road when you, the seller, discover your "Rare and Vintage" whatnot is DOA.
