Even within the 680 series of guns there’s such a big window depending on used, new, condition, barrel length, screw chokes or fixed, etc. I’ve seen old fixed choke 686’s go for $1000 to 687 EELL’s at $8000.00.
I really like Etchens. They know their stuff. And can help with fitting. You could call Etchen and see if they could price match the one in the Basspro link. It’s currently on sale.

Full disclosure, I have no affiliation with Etchens. They’re the biggest Beretta dealer in the country for a reason. They know how to treat the customer. They understand it’s a big purchase for the customer. Whether the gun is a $1000 or $30,000.
Adjustable comb model.
