Aftermarket Radiators

I'm repairing damage to my car at the moment, and I'd like to replace the radiator because it's bent. I'm wondering what my best option is. The car will eventually have an evo 16g on it, so my cooling needs won't be extreme, but with my frame bent the way it is I think I'll need a slim radiator just for safety/clearance.

I've seen Fluidyne, Koyo and no name brands-- what's the way to go? It looks like the Fluidyne is the only one that has full metal construction, the others are plastic and metal like the stocker, is this a big deal? Since I have an auto I'm not sure if I need extra ports to run transmission cooling lines. Do I? Thanks.

You do need cooling lines for your auto tranny, most aftermarket just make one kind for auto and manual. So if you where manual you would leave the rubber seal caps on the lines (I put small clamps around them just for peace of mind). I also don't know how you will mount your radiator with a bent rad support, might be a good idea to get that straightened.
