Optima value?

[BlackWatch]

I'm looking at a trade for an Optima 12 ga over under with 6 chokes and snap caps.
Excellent shape, any idea what it's worth? I believe owner said he paid $850 or $900 new.
Thanks

I just saw one pop up on my newsfeed for 650$

I'm searching and finding them new for between 700-800 before tax
