I saw several in the fall at one of the Eagle Arms gun shows. Don’t know if they go out your way but I think they do go out towards Gettysburg.
The ones I saw were used, but not abused. Two had the box and instructions manual.
That is important since the first couple times you break it down getting the spring back right is a pain in the butt.
I am not even sure you could buy a new one from the shop anymore.
Someone mentioned about having jams with their .22 My brother had the same issue with his retta and narrowed it down to the gun not liking HP's. Now that he uses regular point rounds he has virtually zero jams
