In my area that's about the going price for a new one in "Wonder Finish". I'd be a little reluctant to buy a "like new" Witness, many of these have issues that can take some work to resolve. I have a fullsize Witness in 10mm with the wonder finish. It's taken a lot of time and money to make it run right, well, almost right. I'm still working on mine. Nice looking and sits well in the hand though.
