Usually as a good rule of thumb, I will not sell something outside of the scrap yard unless I am getting double the price I would get for scrapping it. I guess I could bend that rule if the something in question is over $60 or $70. I tell myself that my time spent selling the part as used is worth at least the scrap value of the item being sold. This way, I do not waste time selling things when I could be out finding more scrap! Keeping these types of rules for yourself keep scrapping as lucrative as possible.
