Choosing a replacement radiator

[John]

I am in the process of researching radiators. It's mind blowing. Right now I am focused on:

Griffin combo direct fit
Be Cool combo direct fit
Entropy combo direct fit (the american made radiator not the china brand)
Dewitts combo direct fit

I was looking at Desert Cooler but heard negative reviews.

Of these 4 -Be Cool is the most costly coming in at around $1400. Lowest of the group seems to be the DeWitts at just under $1K.

Can anyone share your experiences with either of these companies or other brands you have had success with? I'd like to stay with the dual core aluminum 1" or 1-1/4" cores AND I prefer it bolts in without modifications. I did notice Direct Fit is not Exact fit and that concerns me. Be Cool makes a exact fit but cost goes up.
