If the cpu was a Core 2 Duo, Extreme, Q series Artic Cooling offers the Freezer 7 Pro as a good lower cost alternative and better then the ThermalTake lineup by far. Unfortunately the only model found for AM2 application by AC was a sad sight to look at!
Zalmans do a great job and one of the most reliable while the prices seen on them are a bit steep even at this time! Once you get one on good you are generally set to go while most will look for a cooler half the price just to get something within the budget on that will work.
(C'mon newegg and xoxide start dropping those prices!)
