The time may have come to replace the radiator on my 300CD.

I suspect the Behr radiator that is in the car may be original.

Any opinions on brand?

Behr: $282
Nissens: $192
Silla: $156

Any appreciable difference in quality? I have a Nissens in my 400E, don't know a single thing about the "Silla" radiator but at that price I have to at least consider it.
