12' Disc - worth buying?

I have an opportunity to buy a 12' Ford Disc harrow with hydraulic lift, asking price is $950. Seems like most 12-14' discs on CL run anywhere from 750-3000 depending on condition. Dealers want more, of course... Given the rarity that I would need to use it, is that a good enough price that I should get it?
