I was browsing eBay and found this:
Radiator Performance Radiator 119 Fits 1987 Mercedes 300D | eBay

An all aluminum radiator for a reasonable price...anyone had experience with these? I don't have an immediate need for one, but I may replace my original radiator for S&G this summer...

First off, the photo is upside down, which doesn't inspire confidence. Is the inlet in the right location? Most Merc radiators have inlets and outlets at opposite corners. How is this constructed? Welded? Crimped? Adhesive? How many rows, and what is the size of the tubes?

I don't know any of those things...haven't looked into it carefully yet.

Not sure if same manufacturer. I think one of our members may have purchased one. Had a small leak I remember easily addressed at a radiator shop. Rad could have been abused in shipping or previous handling though. Maybe poor quality control but it was cheap enough at that time.

All welded construction to me is better than seals between header tanks and core assemblies. Although there is probably less issues with the seal types to really be concerned about today.

Had a more careful look and this one does not seem to be quite the same as the one I posted about. Looks like a seal type.
