aluminum radiator

what have you guys seen works best in style and brands of aftermarket aluminum radiators. will be using a very high flow electric fans set up for late model vechicle.
thinking very large 2 core with like 1.5-2.0 tubes. but not sure about the aftermarket brands, i did have a large 3 core on my old bronco from champion raidaor,but ran hot down high way. may have been just the truck. looking to get a decent one but am not going to pay 400-800 for a giffin, or dewitts, or ? any experiance with them?
will be street car/ a./t, with a/c and p/s...built 318...
