The collest (no pun intended) radiators I have seen are the 4" ones sold on various overclocking sites. The funny thing is is that I found out they are really power steering fluid coolers for automobiles. They are made or named Tru-Cool but I can't find a homepage for the real manufacturer.
They are usually sold alongside Hayden radiators but I dunno if that is the real manufacturer. They usually only cost about $35. Not too shabby.
Try this link: I dunno if it'll work because ist's a cgi addy.

hi!I need to find a cheap radiator to cool my watercooled athlon slot A [email protected] the web i found terrible prices only.Is it possible to bild one from junk yard parts?
YES! There is an article on the main page (under watercooling) describing how to use heater cores from old cars as radiators for your computer. Just make sure it's clean. See this link: http://www.overclockers.com/tips250/
On my watercooling system I an using a transmission cooler it cost me $21 at a local auto parts store. I am in the prosses of building another system and am using a heater core out of a Datsun. If you will go to a radiator shop and explain to them just what you are trying to do they will probably be very helpfull.
Hope I was of a little help; and good luck!
cheap radiators can be found at junkyard shops, once you get one just clea it out really good with like a spray hose to get any junk out from the inside, run it for a long while to mak x-tra sure there aint gonna be no juk floating around in your water cooled system
