Are you used to shooting right janded rifles left handed? Have you shot left handed rifles before? If not, I suggest finding someone with pne who will let you try it.
My dad lost sight in his right eye when I was a kid. As long as I can remember, he shot right handed rifles left handed. When we opened the shop in San Antonio, I decided to order him a left handed Remington 700. He hated it. None of the controls are where he is used to.
I'd do $800 for the 7mm and $700 for the 257. The 257 is a bit more "used" and has marks and scrapes on the stock. There's other pictures on my imgur account, I think you can click on the pictures above and it will take you to them.
