As an avid Craigs list buyer and lowballer.. you have to remember.. it is a yard sale, one person is selling, the other buying.. the buyer has no idea how bad the other needs money nor if they have done the real research. Most of my low balls are what the product is worth to me.. and I am the one with the money;-)
I try and sell things prices as I would offer for it.. even if I could get someone to pay more..
IN72 worth $200, add the other stuff maybe I would go $300 if I was in the market ..
Just post it and see what happens.. wait a week and contact the people that gave you their phone number and other info.. they are the ones that really want it..
