Well, bought my son one, a few months back in 243, which is a little more popular than the 260, i think.
it was in very good shape, and only shot a few times by the mans son. He wanted $775.00 for it with scope.
I got for $650.00 cash...nice Nikon Monarch 3-9 on it....
Not sure what the 260 is worth, but hope this give you a decent guide. I thought I got a decent deal.
