I had two until a month ago. Sold my spare to a local guy for $750. which is $300 more that I paid for it new several years ago. I kept the best one, mine has a threaded barrel and is suppressed, I also put a Choate folding stock on it. Still have the original too.
When I saw them they were running about 400 or so new IIRC. You did darned well. I KNEW I should have bought one.
