I bought mine for under $200 on e-bay and it was new. I love it!!!!!!!!!! Cools better than the 3 core copper radiator with electric fan that I had!
Even the fan shroud bolted right up! Only problem I had was the upper tank hit the radiator support when bolted up so i had to put some washers behind it to shim it. Just dom a search for Roadrunner radiator on e bay and you will find one with a buy it now price for around $200.
