Radiator Replacement Options?
 

I've been looking for a new radiator for my 2001 Altima (automatic) since it started leaking out the top last Friday. I don't want to buy yet another plastic one but all I've been able to find was one from an ebay store called JSR Cooling. Does anyone have any experience with this brand or know of any from a more reputable source? Or are All-Aluminum radiators not that much better than plastic?
