Best place to buy an all aluminum radiator for 2008 H3 Alpha?
 

I have 65k miles on my Alpha and I have no leaks but I'd like to stop pressing my luck and swap out the radiator for an all aluminum version. Ebay has some under $200 and I found this one for $145:

OEM# 25964054,25964053 All Aluminum Radiator for Hummer H3 2006 2007 2008 2009 2010 All Engine - Rakuten.com

I'm not going to spring for a $500 unit so did anyone have any luck with another source?

Thanks.
