I would think some one would pay as much as a new one. So 400 low end 500 high end. I personally would not pay more for those upgrades because I do not really care for them. So if I was in the market for a used madison I would pay 300 low end for this 400 hi end. You only need one buyer to make a sale. If you take time to sell it and do not take the first offer you will prob get a fair amount.
