I bought one last month in very good condition, but without the Front Volley Sight Dial Indicator and some arsenal repairs. See: http://www.gunauction.com/buy/13380393
For a fair market value, GunAuction.com keeps its history of bids for over a decade. Google: "gunauction.com, P-14" and check prices. Be sure to look at dates of sale to gauge the value today versus 10 years ago.
