Well I got the Denso installed today. It looked to be a pretty comparable replacement to the OEM one - probably not quite as good - but no worse than the old one with the amount of road debris that was packed in there. I think there's a small sample of every leaf, bug, and bird feather that we drove past in the last 122,000 miles on my garage floor right now.
The Denso unit was a very good fit. I think the studs that fit into the bottom spacers might be slightly smaller, but that's the only real difference I noticed. Overall, I was very happy with how it all went back together!
The best part is the price... I paid less than $17 for it on Amazon
It was listed under "Amazon Warehouse Deals" which I think is their division that deals with returns. The box had a little damage, and a couple of fins were bent - but the damage was very minimal.
Here's the write-up.

By the way... the problem with the OEM radiator was a hairline crack on the front side of the top tank.
