Need a good cheap heatsink

I'm going to be building a new pc for my sister, and I'll be putting in a duron 1.8 in it, but it doesn't come with a heatsink. The case is going to have crappy airflow, so I want something that will keep the temps reasonable. Thanks in advanced.

try that one, personally I like tmd fans and it isnt too loud.

the kindwin from newegg is solid copper and has good air flow of 42cfm and its only $10.99

For stock cooling, I use the Speeze WhisperRock II. It has a big tapered aluminum sink with a low RPM ultra quiet 80mm fan on top. I'm doing a small overclock on it right now and don't get past 40 load on it. And at 26dba, you can't even hear the thing.

9.99 with free fedex at newegg.

I've also heard good things about the kingwin that was mentioned. But have no personal experience.

I've used both of these with good results:
