I actually bought a 2 core aluminum off line from champion Radiator (E-Bay). Good quality and I have a few buddies running them over here. Lifetime warranty against defects, and if it doesn't cool your rig they will upgrade even if you have used it in the car. I bought a second one for my delivery that is a 4 core aluminum. The 2 core was on sale for $175 and the monster 4 core was $285. I have the guy's info here of you want it.
Now if the snow would go away I could drive it some more and make sure all is good.
