Well, you'd be looking at a Vantec IceberQ 4 for the Radeon 9600 ~ 9800 series GPU, LED illuminated copper fansink (similar to what was originally fitted), TigerDirect (currently) have them for $15.99 USD
but as far as postage I'm not aware what the fees will amount too
As far as recommendations go, I fitted one to a GF2 MX400 over 18 months ago and it's still running fine 24/7, additionally I just purchased it's bigger brother Pro variant to replace the ThermalTake POS cooler on my GF4 Ti4200
Alternatively, Xoxide.com are selling the original Vantec IceberQ (CCB-A1C) VGA/Chipset all-in-one copper cooler @ $11.99 USD
, these are also great little coolers I used the aluminium variant to replace the crappy POS (IceberQ knock-off) Abit fitted to their NF7-S series motherboards, additionally Vantec lists this fansink as a compatible replacement cooler for the Radeon 9200 ~ 9800 series GPU
Neither will break your budget greatly & both are nice coolers which will serve you well, though for my money I prefer a little added LED bling!
