My local O-Riellys has a 1 row for $136 and 3 row for $249 - both have lifetime warranty and appear to be all metal...

We have an old-school local radiator shop I like to use also, they can usually match or beat the auto parts on new stuff and sometimes can fix old radiators. (great place for gas-tank cleaning and restoration too!!)

I have MANY 'lifetime warranty' parts on my junk - I promise they never thought I'd pull out a 10 or 15 yr old reciept and get parts for free, but the counter guys don't mind at all! The point is fleabay is infamous for inferior parts with much hassle required for exchange - I buy local every chance I get.
