You'll have to decide which route to take. The modern replacements are usually aluminum and plastic so I always have my old ones rebuilt at the radiator shop so I end up with a proper old style copper/brass radiator.

If you found a mint condition used copper/brass unit for 90 bucks, that would be a great deal. Just make sure its nice and clean down inside. You will pay more than 90 to have yours rebuilt with a new core.
