Evaluation help needed! Where better to ask?

I've been offered a mint Kimber 82C Stainless (possibly with box; could pass for unfired); Warne bases and rings; two extra four round mags (total of three). Owner states he's fired fifty rounds through it, but there is no visable wear or marking. He's selling it to fund a Cooper.

What is a fair, real-world value; assume no box? Your input is appreciated.

(I'll enter a duplicater post on the Kimber Forum.)
