You make never get one.
When these models came out when released, I predicted that the resale price was going to go through he roof on these models.there were only 13 3rd rail and 18 2 rail. One on E bay went for 2300 this week for the 2 rail version with 23 bids. I have been told one person has already cornered the market on the 2 r versions. He is making different models to have a variety.
