Probably a $300 rifle in my area if it has signifigant wear. They are very well built rifles and were expensive to manufacture, one of the reasons they were discontinued. The .25,.30,.32 Remington were designed to be direct competition to the .25/35,.30/30 and .32 Special which were loaded in the 94 Winchester. Ballistics of the two sets of cartridges are identical with the main difference being the Remington rounds were rimless to work in Remington's pumps and semis. Ammo is getting hard to find for the Remington trio and this hurts the resale value as well. The only model 14's that I have seen go for high prices were a pair that were in about 98% condition, desirable for Remington collectors.
As for the problem mentioned above, many don't realize you can't baby a pump when operating it, slam it back and forth, that is the way they are designed to operate. Even my father's old 760 Remington in .35 Rem. will not feed properly sometimes if you slowly operate the pump.
