they might be worth 200 bucks, they might be worth throwing in the trashcan. There are so many of them out there that they realy aren't worth much. The shop I worked at in California had about 100 pair of good used ones on the rack. We would sell em for 50 bucks a manifold. If I was gonna puy a pair on Ebay I would set the reserve at 75 and if I got more then that I would consider it a good deal.
