I used a DeWitts LSX Modified Radiator
Made in the USA with a Guarantee.
I used the same company for my Corvette. I haven't heard of a single complaint from this company. The LS bare finished radiator is $900. It doesn't come with any fans.

The ice black version with fans is $1600. I paid $1200 a little over a year ago.
I previously purchased a China radiator before going full tilt.
It was advertised for our trucks and didn't even fit the factory bracket locations.
The shroud was too close to the radiator as to make much of the surface are ineffective.
The Dewitt even has flaps that open when you are at speed to keep the need for the fans down. Lots of options.
Even some keep the stock radiators and use the long cross over hose like on the trucks.
The bleeder hose from the heads and be added to any hose using the adapter found on eBay. Picture attached.
I found the inexpensive radiators a frustration I didn't need.
Do what is best for your budget and frustration tolerance. I found it only hurts once if quality is purchased.
Cheers.
