All Metal Radiator??

I have a 94 full size Blazer, 350 engine. I am looking for an all-metal, quality radiator (like GDI as an example). Does anyone know where one can be found? I have replaced the rad 4 times and it is getting OLD.
Help....
Thanks in advance.

Here are a few options from BeCool - BeCool Direct Fit Radiators for 92-94 Fullsize Blazers - Summitracing.com

But do be prepared to pay a bunch for one.

Thanks alot for that reply. But I am realy looking for a standard radiator, (not custom made high performace), factory spec type radiator like the one that came with my truck.the original radiator was a metal tank metal and core, but all replacements I can find are plastic tanks. I  feel certain that someone sells a all metal radiator just having no luck locateing. Anyone else have any ideas where I can  look?

I see them on ebay all the time for like $125...I would look there.

Check this link they supply radiators to Summit Racing:

go to the top bar highlight the "Online Catalogue", there are two options 1. Ready Rad 2. Modine, go to Modine. They will ask for Make Model and Year then scroll down till you find what will fit and the check construction type and look for "copper/brass" and that should work... and I checked with Summit Racing and all you need to do is search for a radiator and you will find the same thing...$144

Have you asked at your local rad shop?
I know when i want heater cores I ask for non-plastic and they can usually supply me with metal within a day.
