I recall seeing them for sale at K-Mart in the 70's for $159.00 with a 4X scope.
I've noticed that current prices for them seem to be inconsistant, perhaps due to the hoopla with Winchester. I've recently seen them from $200-$450 and the conditon doesn't seem to have an influence on the price.
Also, I've seen more 670's for sale in the past 2-3 months then I've seen in recent years. Again, I suspect folks are trying to capitalize due to whats going on with Winchester.
I've heard them categorized as the "poor man's Mod 70", but I don't think that lable means they are any less then gun. Just as Mr. Foster stated, they had hardwood, rather than walnut and a blind magazine.
