B&K Reference 200.7 S2 any idea on fair price?

Any idea on a fair price for this. I bought this in 2008 from first owner. He said he had a couple hundred hours on it. I used it for 2 years, probably a few hundred hours. Moved to new house. Lost my home theater, Due to wife. Been in box for 2 years now. Figure I am never going to get to use it again. Might as well send it to a new home. In great shape. still looks new to me. Any thoughts on price. thanks in advance
