aluminum radiator, ebay or entrophy?

[jrigheimer]

looking to get an new radiator. mine seems to be shot the temp goes up pretty high in traffic and inside it looks to be corroded and the fluid is rust color.
so far i have come up with two choices my price range is around $300-500. both are 2 row with 1 inch tubes and both claim they can handle up to 700hp.

i like the ebay one because it has fans, but i don't know if those fans are any good and i would also have to spend money on a controller.
