I have been looking for some full doors, on ebay (overpriced) they run about 600-900 per door depending on condition. I have seen a few sets used (on the forums) going from $1500 (for 4) to $2500 (for 4). You will most likely need to find someone who wants the color you are selling otherwise it can get expensive for the buyer to have them painted.
